The more I see new "homeworky"' questions rolling onto the site, the more I like your diagram and the draft thingy you're working on, @ortho

The strongest P-O bond is present in which molecule ,F3PO,Cl3PO,Br3PO?
 
7:06 AM
Look up Bent's rule.
 
Do you have any entrance exams as tough as the JEE? @M.A.R.
 
@skillpatrol We do have an entrance exam which has its own complications
I wish I was taking JEE
 
7:21 AM
Is it as tough as they say?
in JEE Preparation, yesterday, by Madhuchhanda Mandal
@SirCumference "The engineering test" which is regarded as the toughest entrance examination in the world
 
@skillpatrol JEE?
I thought you were Indian?
Well, students have this thing about always exaggerating how hard their studies are
 
True dat.
 
Who decides how entrance examinations are hard?
How is "tough" even defined?
 
By the number that pass.
 
Questions like that make me thing either that guy is making this stuff up, or the results aren't reliable anyway
@skillpatrol I don't think it's based on score, but based on position among other students
 
7:35 AM
The total number of people who take it is huge.
What about China?
How do their numbers compare?
We could try an EntranceExams.SE :-)
 
Nice site to meet people I'm gonna downvote
 
@skillpatrol Eh, I dunno
I don't their system has a prevalent entrance exam
 
9:09 AM
why, that's the first thing I do in the day, everyday...

Q: The Nomenclature Of Poly substituted benzenes?

Pranav I am confused as to the nomenclature of poly substituted benzenes. Would more preference be give to to priority order or the alphabetical order? In this pdf, 4-aminophenol has been cited as more correct rather than 4- hydroxyaniline. However, there are some websites which site the other one as mo...

Can someone help me here??
@skillpatrol @M.A.R. JEE is tougher than the entrance exam in China, btw. In China, they have an exam which selects children for selection in govt. jobs, which along with added benefits that such people get, is considered a pretty big thing in China(as far as I know).
 
@Pranav it's just been four hours, chill
that said, if you give me a bit of time to look up the relevant portion, I can write an answer
 
@orthocresol Yea, I know but generally my questions are answered in an hour max, so I think I am expecting bit too much from SE. Sorry about that.
 
@Pranav depends on the time too, theres usually more activity later on in the day
 
@orthocresol Well woudnt "later on in the day" depend on which country you are from? Or should I assume this as the according to the US time zone?
Its already 7 here
 
yes, and it's only 2:30 here, and it's a weekday
 
1:39 PM
@orthocresol Agreed. Btw can you pls help me with this too?

Q: Melting points of compounds?

Pranav Compare the melting points of: 1) $\ce{BeSO_4}$ 2) $\ce{CaCO_3}$ 3) $\ce{BaCO_3}$ 4) $\ce{SrCO_3}$ Okay, so there are a few statements given by my teacher: 1) Thermal stability of ionic compounds is proportional to counterbalance the effect of electropositive field of ca...

This one has been bugging me a lot
 
I'm not sure about that one. If you look it up on wikipedia they seem to behave differently. some decompose and some melt and I do not know how reliable it is.
In the absence of other data I would have assumed the same as you, i.e. 3, 4, 2, 1.
 
Oh so that's settled it for me then. Thanks!
I will now ignore google on such questions........
 
solid state stuff is usually made complicated by the existence of different crystal structures
 
Yea, my sir did mention that somewhere. So theoretically, in an exam the ans. would be what I got but in real life things get very complicated, right?
 
I would say so.
Theoretically without doing experiments, 3421 is certainly correct.
 
1:43 PM
So google displays values from wiki, and since wiki displays experimental data, the and so the answers mismatch.
Thanks. Thats what I thought too.
 
@M.A.R. Maybe a polypropylene bromide suspended in tolune
 
Google can be incredibly unreliable too, for example if you try searching "bond angle in water", it tells you 109.5.
oh
they changed it
 
Oh i see
and obviously it isnt 109.5
 
They used to write 109.5 which is obviously wrong. I wrote in to them to complain, maybe they changed it.
 
cz of the lone pair
yea. VSEPR theory right>
 
1:45 PM
Mmhmm
 
@orthocresol Wow. Oxford. How exactly do you get into oxford. Do they have an entrance test?
 
Not when I applied, but now they do.
 
Can people from other countries give the exam too?
 
Yes, of course
Now, your aminophenol question is a duplicate, it seems...
 
Oh. The link?

Q: Nomenclature of benzene derivatives

TinkidinkiIn several places, I have seen that while naming benzene derivatives, no priority for substituents is followed. Eg: 2-hydroxy aniline= 2-amino phenol. Is there no order? Or is the order different from aliphatic compounds?

 
@ortho Thanks!! So should I delete my question now?
 
Up to you, I am not sure whether you can close it as a duplicate by yourself.
 
Would deleting it reduce the reputation I got?
 
@Pranav Yes
 
Hmm then pls give me a minute. Then pls close it as a duplicate yourslef, if you want to
 
1:56 PM
@M.A.R. if you flag it as dupe, he can accept the dupe suggestion when he wants, and community can close hammer it

Q: Why does one of Dalton's compound elements with oxygen and phosphor consists of four atoms instead of two?

bluppI stumbled across a peculiar detail while reading the chapter about the Chemical Revolution in Bowler and Morus' book Making Modern Science. According to this book, Dalton argued that compound elements are created in the simplest possible way. For instance a compound consisting of equal number ...
