No the order will be D>C>B>A because the RDS is the "formation of carbocation" and hence the rate/reactivity depends upon how stable the first carbocation formed is ..Not on further rearrangement.This is a very important thing to note in SN1 so hope this clarifies any doubts!👍😊
@@harshpreetkaur5701 No, because it can be further rearranged doesn't mean that it will form fast ..For this you have to look to the first carbocation that is forming because Rate only and only depends upon that (not on whether the other one could rearrange to become even more stable than the other one or not) and for the formation of "first" carbocation D is more stable...Hence the order is D>C>B>A. If you have any further doubt you can watch "SN1 reaction in reaction mechanism series of channel "Physics Wallah"👍

Bond is made of two electron one from c and other from br as br is more electronegative it will drag electron towards itself so it drag electron of c also .so it gain negative of electron pairs
Sir !! Please give lecturers on board in the way of art of teaching ..... I mean by explaining on board by standing Sir!!! Please sir it does not mean insulting you sir ... Sir!!! Please sir understand .....in that way we can get more interest sir... instead of on computer screen explaning... .. Sir !! Please sir teach in that way Its not only my opinion sir many others ( my frnds) [I mean like way in goc epic] Please sir !!! 🙏🙏🙏🙁🙁🙁🙇🙇🙇
Bro - I don't have that huge board at home - we are in lockdown. We shall continue that system once we all can go back to the office to work. I hope you can understand the situation and adjust for the time being.
@@CatalysisbyVedantu We should be thankful that atleast we are getting free quality education at the cost of just sitting at home even during this lockdown period

The great session which i haven't wasted a single SECOND ! 😍 TQ A LOT SIR ji ❤
Sir Wonderful session with lots of stuff
Awesome class sir .. I understood SN 1 mechanism very well.. Thanks a lot!!!!
thank you so much sir...carbocation shift was most easy to understand👍🙏🙏
Thanks sir mind blowing session
super awesome lecture sir
Thankyou sir super class.
superb class sir.. hats off!
Uhh r the best sir ♥️ You teach so well ... Your all series are epic 🤟
Awesome session sir
Really helped me a lot
50:44 for sn1 will the order be C>D>B>A. ??
Bcz in C hydride shift takes place which is more favoured than methyl shift in D......?
No the order will be D>C>B>A because the RDS is the "formation of carbocation" and hence the rate/reactivity depends upon how stable the first carbocation formed is ..Not on further rearrangement.This is a very important thing to note in SN1 so hope this clarifies any doubts!👍😊
@@akshatsachan7810 but carbocation will be more easily stabilized in C ...thus favouring its formation
Isn't it?

@@akshatsachan7810 thanks
Thank you sir , your sessions are really helping in revision :)
sir in last qusstion NH3 is a polar protic solvent right? then SN1 should be major na?🙂
Nice
If the phenyl shift does not happen then the carbocation gets satbilize by resonance provided by the benzene ring. But this is not happens why
Sir how can we make all these things useful in real life sir.
By giving exam and securing a good rank
@@awesomechemistry7844 thankyou bhai can we use this things to solve our common problems.
@@anandapatmanabhansu YEAH IN GAS LINE COMPANY IN ARAB COUNTRIES TO REDUCE USAGE OF CYLINDER WHICH IS LIKE A MINI BOMB,ALSO IN PETROLEUM RESEARCH IN MANY COUNTRIES ,MANY PRATICAL APPLICATIONS ARE THERE
@@awesomechemistry7844 thankyou bhai we will all study and make it more useful.
The example on 37:17 why are we doing that hydride shift? Cause even after the hydride shift we are getting a 2° carbonation only.
The carbocation formed after shift will be resonance stabilised
Sir,are ring expansion and ring contraction important???
41:00 whether this question show racemic mixture
Pls give a heart
Thanks sir
Sir bs ek guzarish, pehle pura organic khtm krna fir physical, inorganic p ana... Kyunki organic hmara thoda weak h
Sir if phenyl is farer than methyl from carbocation in certain compound then what we can take as first preference methyl or phenyl
As I said - we look at only the adjacent carbon for the rearrangement
10:20 why bromine with a -ve charge with lone pair?
Bond is made of two electron one from c and other from br as br is more electronegative it will drag electron towards itself so it drag electron of c also .so it gain negative of electron pairs
9:29
45:41
sir,,will the rearrangement takes place in carbo cation during sn1 mechanism????
Bro - watch the class carefully and completely please.
sir in the second question at 55:00 mins
nh3 is weaker nucleophile than cl-.but why sn2 is major sir please reply
did you get it answered
Sir !!
Please give lecturers on board in the way of art of teaching .....
I mean by explaining on board by standing
Sir!!! Please sir it does not mean insulting you sir ...
Sir!!! Please sir understand .....in that way we can get more interest sir... instead of on computer screen explaning... ..
Sir !! Please sir teach in that way
Its not only my opinion sir many others ( my frnds)
[I mean like way in goc epic]
Please sir !!!
