Hello

8:34 AM
So many newcomers come to Chemistry.SE only for asking question to prepare for exam ...
I don't know why other SE like Math.SE has many nice questions compared to there ...
I know they're in exam. Asian people will face exam because this month is the end of semester in high school (include me)
Why don't they ask their questions in Yahoo! Answers or they hire private teachers or other way -_-

@Ridho What does that mean?
@Waffle'sCrazyPeanut Your blog inspired atleast one guy.
 
@user223679 Heh, thanks :)
 
@user223679 I don't know why SE is targeted mostly for asking homework questions.
False advertisement maybe
 
@Ridho Apparently, at least some of the audience encourage it, which in turn encourages them to post more
 
@Waffle'sCrazyPeanut Most newcomers only ask 1 ~ 10 questions, then disappear from SE. That's making SE is a disposable site lol.
 
@Waffle'sCrazyPeanut Btw, its not me. I am still trying to pickup speed....rather I was talking about this guy:
@Ridho No. If those 1~10 questions are good then it doesn't matter.
 
10:55 AM
@user223679 Oh, nice :)
@Ridho Well, you should have a look at Physics.SE. Even though we offensively close HW questions, we still get them at a steady rate. On the other hand, math has somewhat less stricter HW policy (compared to us) - so, the users who visit Math.SE often get to think that all the other sites are similar (since everything is Stack Exchange)
 
@user223679 I don't know why those bad questions are still only closed, not deleted ...
 
@Ridho Why do you want them deleted?
 
@Waffle'sCrazyPeanut Maybe because Math.SE is fulfilled with LaTeX formats, so newcomers will think again to ask HW question there
 
@Ridho That's a good thing. Closing them might be an example for showing new users the effect of posting a HW question on the site again.
 
@Waffle'sCrazyPeanut IMO, physics is more strict than chem which is more strict than math.
 
11:00 AM
Yep
 
In physics, one cant ask whether his/her approach is correct. Chem accepts this kind of questions and in Math... one doesnt need to show the approach, just post the question, you shall get the answer in minutes.
 
@user223679 That's why there's Physics Overflow (not in SE network) and MathOverflow. The questions are not asking, but like researching.
 
@user223679 Not quite. Even after spending 2 years in Physics.SE, I've never understood our HW policy completely yet
 
@Ridho I have no idea what your last message means. How did PO and MO come in when we are talking about HW questions?
 
@Ridho Uh, PO is not actually SE's. It was formed by the users who didn't like the environment here
 
11:09 AM
It was something like a rebirth of TheoreticalPhysics.SE I guess.
 
@user223679 Because Physics and Math SE have purity from HW questions, PO and MO are there. It's just my thought
 
Again, they have much focused concentration in the fields
 
@Waffle'sCrazyPeanut Maybe because idea of PhysicsOverflow.SE revoked in Area 51 SE lol
 
When I said "one cant ask whether his/her approach is correct", I meant approach to the HW question they are solving. Hope that clears it. @Ridho
 
@Ridho A few months ago, there was a war - you can think of these as its consequences
 
11:13 AM
@Waffle'sCrazyPeanut Link to the war please :p
 
@user223679 But should Chemistry.SE has rule like Physics.SE? I know Chemistry.SE is just out from beta.
 
@user223679 I think it's been totally closed & sealed from the outer world, though I'm not sure. You can still find some relevant meta.SE posts

Q: Physics is rotting into a bad situation, a request for community manager intervention

Vanished UserPhysics Stack Exchange is experiencing the throes of very bad days. Lots of main and key users (compared to the total number of them) have left or are leaving. Examples of the community destruction include, with the leave: Have we lost the necessary critical mass of professional physicists? I...

^^^ A relevant one (though that was a teensy-beensy bit of the war) :P
 
@Waffle'sCrazyPeanut The shog9's answer is very painful, tbh
So experts and professors are leaving Physics.SE because of full HW questions?
 
11:41 AM
@Ridho Not exactly. The problem was much more complicated than that
To be precise, disagreements & arguments turning into harassment -- that gave birth to all the other problems

@getafix Oh hullo! Welcome to the chatroom!
Sorry that I couldn't respond soon enough.
I was dreaming when you posted that. :}

Q: Why does this happen?

user3267530I was reading N.C.E.R.T. class XI part 2 book and chapter Hydrogen,where i came across this Statement. Loss of the electron from hydrogen atom results in nucleus (H+) of ~1.510–3 pm size. This is extremely small as compared to normal atomic and ionic sizes of 50 to 200pm. As a consequ...

 
Hullo @Fred!
 
Hola
 
It happens cuz it happens.
Positive charge concentration so high!
 
This is one of the reason why Hydrogen have special place
 
Hydrogen is special.
It's part of the water family!
 
2:03 PM
@M.A.Ramezani does not exist without Hydrogen! :-)
 
Yes. That's the second importance.
I'm highly thankful to Carbon.
He's a cool guy.

Hi everyone.
 
Hullo!
I think I'm the only one here right now, but anyways
Welcome to the chatroom!
 
Yeah got the chat privilege a few days ago
 
Yay!
 
I am 2nd year undergraduate student
from India
 
Oooh.
That means 10th?
 
4:07 PM
10?
I am B.Sc student
 
Well I dunno what that is, but it sounds yummy!
 
Bachelor of Science
 
Oh!
Haha, well, I'm studying 10th, or studied.
 
hmm... basic chemistry then
 
Yup.
But we do get some regs that are real cool guys...PhDs and stuff.
 
4:10 PM
nice!
 
@Martin, @LordStryker, @Nicolau, @Ron etc.
 
do you want to study chemistry after completing school?
 
Pretty much everyone but me.
@Papul I wanna be a pharmacist, or a doctor, so yeah, kinda.
I love chemistry. That's why you find me here.
@Papul whaddya study? Organochem?
 
No specialization as of yet
I study all the three branches
 
Oh, so your main thingy isn't chem?
What's your major?
 
4:14 PM
It is. My major is chemistry. But no specialization as of yes
yet
 
You can edit chat messages here!
Hullo to you too @Kartik!
 
@M.A.Ramezani Hi
 
Oh my, a guy from TeX.SE!
@Martin would be proud.
@Lord too.
 
@M.A.Ramezani I was from TeX 1 year Earlier
@M.A.Ramezani Now I think I am from Chem
 
Hah!
 
4:19 PM
@M.A.Ramezani Can you tell any good online book for inorganic chemistry?
 
Online?
Ah damn! Let me think...
 
@M.A.Ramezani I mean Ebook
 
I know...The problem is I dunno...Let me think...
 
@M.A.Ramezani Ok if you dont know then no problem
 
That's not OK for me...I'm searching chem.SE.
 
4:24 PM
what part of Inorganic chem do you want to study?
There isn't one book for all in Chemistry generally
You have to consult a lot of books
 
@Papul Okk so then tell all the books
@Papul I will study all of them
 
Even I don't know all of the books
:P
 
@Papul Any one?
 
@M.A.Ramezani how do you edit chats?
ok
 
@Papul Ctrl-Up arrow
@Papul Any part
@Papul From the beginning
 
4:27 PM
@Papul Hah!
@Papul you can also hover over a message and see star, flag and reply buttons.
 
My proffs recommend reading the first few chapters of Huheey, J.D Lee and Shriver Atkins
to clear concepts about the very basic stuff about bonding and structures
 
@Papul Are they available online?
 
many students lack concept of the following stuff
 
Atkin's physical chemistry...Yeah that's nice.
 
@Kartik that you have to check for yourself
 
4:29 PM
But I don't think it's a free ebook.
 
Ok, I'll check
 
@Katrik what level?
For what level do you need the books?
 
@M.A.Ramezani no so nice actually. I find it lacking quite a few things. Always end up referring other books.
 
@Papul What? You mean Atkins'?
 
@M.A.Ramezani I know some of the basics, like bonding, Quantum theory, orbitals, etc But not things like oxidation / reduction / etc
 
4:32 PM
yeah Atkins Physical Chemistry
 
Why don't you cover the more advanced textbooks from your school?
Oh look!
Sherlock Holmes has answered this question.
1
A: Introduction to Chemistry Textbook - Theory based

Sherlock HolmesSilberberg or Zumdahl Chemistry are great introductory reference books in my opinion. They cover the topics in just the right amount of depth and explain concepts extremely well, I highly recommend it. Inorganic Chemistry and Physical Chemistry by Peter Atkins also seem to be decent (though ve...

 
@Kartik even I thought I knew the basics and then I started reading these books and realized I didn't know so much
 
I wonder who was the murderer this time.
 
@M.A.Ramezani Actually I am looking for online books because I have already read the books of my school
 
@Kartik Have you read the books of older students in your school?
 
4:34 PM
@Papul I know, I thought I knew the basics till last year but now I know the truth
 
@Kartik have you read the book I told you about?
 
No, I'm still finding it
@M.A.Ramezani No, I have the book only of my class
 
I mean at school
 
@Kartik Then I recommend doing it.
 
@Papul No we dont have that book at school
 
4:35 PM
there is a great website for downloading pdfs of paid books
but I am not going to post it here because it is pirating
 
@M.A.Ramezani Actually In our school we have started 11th class this year and we are currently the seniormost class
@M.A.Ramezani So there are no older students
But I'm still finding the books
 
piratesofthecaribbean.com?
 
And I do not know the rules regarding pirating here
 
@Papul Good call.
@Papul Everything here is under copyright.
OK then @Kartik you know what I would do?
I won't look for one book.
 
@M.A.Ramezani So what would you do?
 
4:38 PM
I'd list the topics I wanna understand more about.
Then search for tutorials on the net.
With a Google search like what's hyperconjugation?
 
@M.A.Ramezani What would you do if you dont know the name of the topics??
 
@Kartik There's so much to learn about the topics whose name you know, that's not worrying for now.
Even if I was worried, then I'd wander chem.SE.
You can find plenty of those topics simply by looking at the tags.
Or taking a look at the newest 50 questions.
 
@M.A.Ramezani Ok, I think that looking at the tags is a good Idea. Thank you.
But another question
 
Am ready!
 
Do you have to learn the names of all polyatomic ions?
 
4:43 PM
I might also ask TeX Qs from you @Kartik. I'm a beginner at TeX.
@Kartik Nah.
Of course not.
 
@M.A.Ramezani Even I am a begginer at TeX. But still ask
 
The standard procedure is to be doing so much chemistry, you'll memorize them by heart.
But some schools/exams/whatevers require you to memorize a specific number of them.
Then, you should ask them what names they're gonna ask from you.
 
@M.A.Ramezani What about the uncommon ones?
 
@Kartik What's IUPAC's red book for?
 
@M.A.Ramezani What is that?
@M.A.Ramezani Oh I got it
 
4:46 PM
Or, you can just search them at Google, or ask them at chem.SE.
 
Ok, thank you very much.
 
As I said, there's nothing important to be missed, unless your school asks you to memorize them.
@Kartik Anytime!
 
That is exactly what I was looking for
@M.A.Ramezani Any open source online tutorial?
 
@Kartik Oh hehe, I've answered that one!
@Kartik Are you aware of the existence of beautiful phenomenons like Wikipedia, chemwiki.ucdavis.edu, hyperphysics and so on?
 
@M.A.Ramezani I was aware of wikipedia but not the others
 
4:53 PM
@Kartik While you use Google to search, you'll run into them.
Tip: Notice the URL of the site you visit.
If you again visited that site some other time, that means there's some useful content there for you.
I'll let you discover them yourself.
That way they'll be tastier.
 
@M.A.Ramezani why do you use food analogies?
 
@Papul That makes it tastier.
 
really a bad thing to do while doing chemistry :P
 
Meh. Nothing happens to a chair cyclohexane.
 
lol
 
ADG
5:53 PM
lol

Oh yay! Tschoppi is back!
I think you guys have good memories with him.
 
 
4 hours later…
10:58 PM
Hey guys, I just needed some help with some bonding stuff. If possible please try to answer my question. Thanks!
 
ron
11:32 PM
@M.A.Ramezani Knowing how much you enjoy cyclohexane, I was wondering if you ever gazed at the beauty of the 4 chair cyclohexanes locked in the adamantane structure?
 
He must really like diamonds then
 
ron
That made me smile!
 
ron
I read your comment in the multiple sigma bond question. Do you not think bent bonds and the ethylene 2-membered ring make sense?
 
I liked your answer, very well written
It was quite interesting, I hadn't seen ethylene that way before
I think it makes as much sense as any other bonding scheme
 
ron
11:37 PM
Thanks, I'm kind of a fan of bent bonds
 
I'm not sure if there really is much point in labelling bonds as sigma, pi, etc, in the first place
Haha
You should get into prismanes then
 
ron
Your right about labeling, but it's like we need some kind of nomenclature so we can discuss things
 
I read a chapter about prismanes in a computational chemistry book, some pretty crazy bonding going on
I understand, it's an approximation of reality which has much use
 
ron
It's amazing how easy they can be prepared photochemically
despite the strain
 
I don't recall very well, but I remember an extremely strained molecule being synthesized by photochemical expulsion of C=O
And it happened "after many, many attempts"
I think it was tetrahedrane, if I'm not mistaken
Or one of its derivatives at any rate, the parent molecule being probably too unstable to synthesize
 
ron
11:43 PM
Worked all day cleaning the garage. It's the last right of passage from spring to summer. We just opened a nice cabernet to celebrate.
 
Hehe, a job well done
 
ron
good to have it behind me
 
11:58 PM
Oh, I forgot to mention, I had a lot of fun taking part of those cyclic ether/alkane boiling point questions
Turned out to be richer than I had expected
