@GaurangTandon @Abcd

Pls help I legit don't know how to do this

@AvnishKabaj even we got this question and you said you got a different paper -_-.

@AvnishKabaj Let me frwrd the solution to you...

@AvnishKabaj SN1, SN2 etc aren't given in Clayden, are they?

@Abcd I said different key

@Abcd they are

@AvnishKabaj Oh, okay. Sorry. I misunderstood.

@Abcd coul you send me the link?

@AvnishKabaj Which chapter?

@AvnishKabaj Link to?

@Abcd gimme a sec

@Abcd the solution

@AvnishKabaj I have posted the picture, is it not clear?

@Abcd no man it's just that I got many wrong

@AvnishKabaj Oh, so you want the pdf of the solutions. Wait.

@Abcd Chapter 15

Nucleophillic substitution at Saturated carbon

@AvnishKabaj Are you able to see this^^

Thaaaaanks

@AvnishKabaj How much are you scoring?

238 :(

Wbu

Total? Or in advanced only?

Yeah

Man

Total

@AvnishKabaj Too many silly mistakes

Advance was for 210

Dont ask my scorre

@AvnishKabaj Yeah, same here.

@Abcd I told you mine

It's fair that you tell me yours

@AvnishKabaj Well ... Don't laugh but $185$ :'( ... I have lost around 50 marks purely because of silly shit !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

@Abcd happens man happens

One of my friends is getting 305

@AvnishKabaj thats a good score

Agreed

@GaurangTandon @AvnishKabaj Why do $S_N1$ reactions need weak nucleophiles?

idk...

As far as I remember(from Peter Sykes) here is the explanation-SN1 reactions have no role of nucleophile in rate limiting step(hence the term SN1).Stronger nucleophiles tend to generally participate in rate limiting step and hence SN2 is favoured by stronger nucleophiles.

As to why they tend to participate in rate limiting step-They have high charge density and hence do not have to wait for C+ formation and can compel reaction to proceed in a single concerted step

@yashasvigrover Are you appearing for JEE 2018?

@yashasvigrover thanks!

Yes man

You guys seem to be from fiitjee?How is the test series?I have heard fiitjee AITS are horror stories :3

Btw,where do you guys live?

@yashasvigrover Different places in India.

@yashasvigrover yeah, 2 of us are from fiitjee and have just entered 12th.

@GaurangTandon What's the mechanism of $\alpha$- Elimination of $\ce{CHCl3}$ to dichlorocarbene

@Abcd no clue :/ it occurs in rimer tienman, but am not sure if there's any mechanism even for this

@GaurangTandon do you have any idea about the hybridisation of Carbon in dichlorocarbene and its structure?

@Abcd sp2? depends on whether it's a singlet or a triplet carbene

@GaurangTandon How would you predict that its a singlet or triplet carbene?

@Abcd idk, never did... :/

@GaurangTandon Are "above arrow things" of reactions given in JEE or we need to learn it

what are "above arrow things"?

i mean the things like promoters, lewis acid/ base, catalyst , temp etc written above the arrow @GaurangTandon

is cope reaction in syllabus?

@Abcd yup, they're important; don't ignore

@Abcd no, just mug it though, hardly ten lines

@GaurangTandon what about pyrolisis of esters/ xanthates

@Abcd never heard of it...

@AvnishKabaj Any idea?

Timer tieman rxn mechanism is important.Has been asked in jee 2 times in passage based

@Abcd I toh don't even know whats a carbene
