@GaurangTandon OK, I'll wait.

1:16 AM

@Abcd i think you were looking at the S<sub>N</sub>1 reactivity instead; because in the right column - which is what we're supposed to look at - $\ce{ROCH2X}$ is not even mentioned

Abcd

1:50 AM

@GaurangTandon Oh what to do now

Avnish Kabaj

2:11 AM

Believe my reasoning?

Abcd

@AvnishKabaj TS stabilisation is also important

There's overlap in TS with almost vacant p orbital of C

I think that should be max in Ar3 case

@AvnishKabaj Dont you remember reading "Substrate is most important in Sn2" from that wiki page

Gaurang Tandon

@Abcd ask on main? :)

@GaurangTandon OK sure

Nice answer! but tell me do you have access to PUBS ACS website and that article? — samjoe 4 mins ago

@GaurangTandon @AvnishKabaj

Avnish Kabaj

No I think

?

Abcd

@AvnishKabaj what to reply to him now?

Avnish Kabaj

@Abcd wait you do have access right you're doing that weird thing Gaurang said

Don't reply

Abcd

@AvnishKabaj yes I got it through GT's site.

@AvnishKabaj Wont mods start doubting?

Avnish Kabaj

What no

No biggie

Abcd

3:23 AM

@AvnishKabaj why

@AvnishKabaj have you ever quoted that way?

Avnish Kabaj

No I haven't

Take it up with orthocresol or someone

No one's going to jail you

Abcd

Now @GaurangTandon needs to tell me what has to be done

Avnish Kabaj

But he may ask you to delete the answer

Abcd

@AvnishKabaj I dont understand why Pub Acs dont allow free access

Whats their problem?

Avnish Kabaj

@Abcd they earn big bucks

Abcd

3:28 AM

@AvnishKabaj Agh! Horrible people

Avnish Kabaj

Lol

Abcd

pub acs should Learn something from charitable ones like Khan academy

They (pub acs) are literally barring people from gaining education

Gaurang Tandon

the short answer is: you do have access.

if he pushes further: just tell that there's tons of ways to get access, for example, my relative uncle happens to be a scientist

If he still pushes, you're not obliged to discuss further

case closed

@DivyankaChaudhari I like your accented Huckel; that's the first thing I was going to fix hehe :P

@GaurangTandon I have replied "I do have access" and then flagged his comment as no longer needed.

Q: Can Hückel's rule be applied to inorganic compounds?

Hückel's rule helps us know which molecular orbital, bonding or antibonding contains more electrons, and it is derived from the same. And on the basis of this, we can find out the stability of the compounds. But, this rule was specifically introduced for cyclic organic compounds to know if they...

By the way, @GaurangTandon, I was checking my docs and I found that I have full set of FIITJEE AITS papers of class 12. You might want to have a look at them? Maybe that could be helpful.

Okay @Abcd

4:20 AM

@DivyankaChaudhari thanks so much! but really am lagging so behind, that I don't even have time to solve the test papers I got from my own coaching :P Though I would really appreciate if you could send exactly two FIITJEE AITS papers with the answer key, I wished to just have a look just at them

Abcd

@GaurangTandon 5 days to mains result, good luck :) !

I didn't expect them to check papers so fast

Gaurang Tandon

haha yeah thanks :D

I have ones from 2014 though @GaurangTandon. Okay. I'll send just two with the solutions.

@samjoe Theres a site which allows access to Pub Acs Papers

The site's motto is:

"No barriers in the path of knowledge"

Gaurang Tandon

Hi @samjoe

Avnish Kabaj

@GaurangTandon I cross checked with another picture on your school site and the other dude wasn't there

Gaurang Tandon

@AvnishKabaj assume $\ce{Ac2O}$ is only 1 mole, because "excess" is not mentioned

Abcd

@AvnishKabaj What is AC2O?

Gaurang Tandon

@AvnishKabaj hehe, nice work

didn't knew I was so easy to find

Abcd

5:58 AM

Capital C is a misprint right?

@GaurangTandon aaah

@Abcd yep

Thanks

welcome

@samjoe you had a question?

Abcd

@GaurangTandon which reaction is this?

Gaurang Tandon

5:59 AM

@Abcd SN2Th, carbonyl compounds

samjoe

@Gaurang you may have followed the convo with abcd, could you please tell me how to access pubs acs

Abcd

@GaurangTandon SN2 or SN2TH what is SN2Th?

Asking because I saw Sn2' Sn1' (notice the ')

Gaurang Tandon

@samjoe short summary is there's a site sci-xxx.yy where xxx is hub and yy is tw. you paste the DOI resolver of any research paper there, and can read it. You can read about that site on Wikipedia as well

it's supposedly illegal, but till now there hasn't been a crackdown on the official owner of that site, let alone the users of that site

there's just an ongoing court case with Elsevier atm

Abcd

@GaurangTandon man but why is Pub Acs So MEAN???

Gaurang Tandon

@Abcd you'll read about it later; SN2 with tetrahedral intermediate

@Abcd ha, read about it on the internet, too many blogs/vlogs about the same topic

@samjoe you okay?

Abcd

6:04 AM

@GaurangTandon send me one good one.

Gaurang Tandon

@Abcd i studied about it back early this year, lost all links, plz just google

Abcd

@GaurangTandon Chemistry is already an Underrated subject and sites like Pub Acs make people away from it more

Avnish Kabaj

Holy guacamole I just downloaded an ACS doc

samjoe

@Gaurang is answer to avnish's question, the option B ?

Gaurang Tandon

@samjoe it's C, because N is more nucleophilic

samjoe

6:07 AM

@Gaurang thanks, i had heard about this website, and sites like libgen etc, but never knew that it gives free access to pubs acs docs..

Gaurang Tandon

@samjoe well you know now ;)

Great job man

Gaurang Tandon

his googling skills happen to be pretty advanced :P

i'm on the left, the short heighted one

samjoe

6:14 AM

cool!

Sid

@Abcd underrated?

@Abcd I don't think Stalking people is a good idea...

samjoe

@Gaurang man I have almost forgotten Oc, can you tell me why N is more nucleophilic? Is it because N is larger than O? also does it not depend on solvent

Gaurang Tandon

@Sid well tbh I should've never used my real name in the first place, and I can't really stop anyone from doing that :/

@samjoe it doesn't depend on the solvent; N is less electronegative, so it can easily give up the electron lone pair

Sid

Also, CBSE has released JEE-M answer key? Any controversies so far? @Gaurang and @samjoe

Gaurang Tandon

@Sid nope, not for me, I'm good

samjoe

6:19 AM

@Sid idk dude, i think result is on 30

Sid

@samjoe result, yeah. I think someone said to me that they released the answer key yesterday

samjoe

@Sid thanks man, yeah its true, just checked

@Gaurang when do we take into account the solvent

Abcd

@Sid Most people I know hate it.

I mean out of all JEE aspirants I am sure only 30% like chemistry

Sid

@Abcd um... That's not what underrated means..

Abcd

@Sid it does mean that, its such a good subject but they dont value it

Gaurang Tandon

6:23 AM

@Abcd it doesn't. you probably meant to say "overhated" or "overdisliked"

Abcd

@GaurangTandon see now^

Sid

There's difference between "not liking" and underestimating something.

Gaurang Tandon

@samjoe for the halides nucleophilicty in DMSO and water

Abcd

ok

@Sid not me, Avatar Shiny found it

samjoe

@gaurang so only for that!!!

Gaurang Tandon

6:24 AM

@samjoe ya

Abcd

@samjoe the order is reversed in DMSO and DMF only

samjoe

@Abcd i know that

Abcd

@samjoe ok

Sid

@GaurangTandon true. But, I think that violates some privacy laws. But, anyway,never use your full name in online platforms.

samjoe

@Abcd haha till now you didn't tell me that avatar shiny found it, you were being cool. Now when sid said stalking isn't cool, you took no time to put it on avatar shiny :P Not blaming you, thats just typical human behaviour.

Gaurang Tandon

6:28 AM

@Sid true that, but it's too late.

I'm irreversibly embossed in this giant web

samjoe

@gaurang will you check mains answer key again

Gaurang Tandon

eh, did it mutate within 24hrs of being posted? o.O

samjoe

@Gaurang not sure what that means

Gaurang Tandon

i already checked it once yester-evening, no clue why I've to check it once again :/

so i probably won't

samjoe

@Gaurang how are yo studying chemisty, man I am ****ed, I am fine with jee mains OC but advanced organic gets me everytime. Last year

Last year I managed to mug up some organic reactions some came directly and I was able to answer oc questions (some).

Gaurang Tandon

6:32 AM

just practice past year papers, that's the only way truly. I also did solve a lot of MS Chouhan; Advanced Problems In Organic Chemistry; 11th ed. so probably that helps too

samjoe

@Gaurang yeah previous year q are the only hope

Abcd

8 mins ago, by Sid

@GaurangTandon true. But, I think that violates some privacy laws. But, anyway,never use your full name in online platforms.

@Sid Many people use it on SE

John Rennie for instance

There is no problem with that

it's just about being "more open "

I am sure people would like to chat and interact with @GaurangTandon who has his actual name more than me a random "abcd"

Sid

@Abcd there's no problem with using your full name. The problem is people stalking you. John and others don't count because them using their real name lends them credibility in a technical SE site like Physics.

Gaurang Tandon

okay guys chill; i'm strictly okay out here; let's get back to some chem in this room

samjoe
