again this halo with cyanide
redoing this question i realised ki isme methyl shift ho sakta hai to make it 2 degree carbocation and that is more stable but it doesnt happen, why?

Ye to direct Sn2 hogya yaha
sn2
Alc KCN?
Nucleophile
Isme dikkat kya hai @Sephrina ji?
Mechanism bheji to thi
Dobara bhejun?
mai pgl ho rhi hu tbh
Are aaram se
have u studied ambident nucleophile thing
hn
2-3 question mix ho jara
Ek second I just read your question
Dekho it’s easy to explain
Hear me out
ok
Methyl shift se stability aayegi due to hyperconjugation
But jab Br nikal jaaye
Tab stability aayegi directly through Oxygen ke lone pairs
From OCH3
They’ll directly coordinate to the positively charged carbocation
och3 more stable than 2 degree?
Dekho ek baat batayo
Agar kisi atom ke paas lone pairs hain
Or uske just saath ek aisa atom attached hai
Jispe positive charge hai
What do you think is the most logical result?
Of such a situation
ofc vo add hoga
Yeah exactly!
kyunki +ve , -ve stable out
And that would technically end the cation
That would be neutral then
hn
To tertiary cation better ya neutral?
Jisko sidha oxygen apna lone pair de raha hai!
for reaction?
Nahi stability pooch raha
stablity to neutral
Reaction to Har stage pe stability ki or jaati hai na
Exactly
To vo form hoga
Rather than a methyl shift
ok kinda got it
And for the whole mechanism
Victor sahab ki khud ki likhi hui bhej deta hun
hn
Jo Mai already 3 baar bhej chuka hun btw
🫠
vo lec mere paas hai
download kar liya hai
Haan lectures dekh lena koi ni
Ye specific example Maine unhe bheja tha discord pe
This is what he sent
okk
Isme kuch na samajh aaye to poochna
hn
matlab ki is particular me mai keh sakti hu ki uh oxygen rather prefer karega uske bgl vale c me double ho uske sath, than it being a cation right?
Yeah you can
It is like friedel crafts acylation
Have you studied that?
Usme bhi same isi tarah ka cation banta hai
We call it acylium cation
Here it’s not exactly acylium
But kind of vaisa hi kuch hai
foggy hai par yaad hai
arene me acetyl add kiya tha
ok okkk
Haan uski mechanism…..
maine mech nhi dekha tha uska
Vo dekhogi to you’ll get a lot more idea about this
Bohot similar hai
ok
mai ik var dekhti vo
Dekh lena
hn
Yup it’s very similar
