+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.It occurs when there's a carbocation intermediate. For example, SN1 reactions
methyl shift is rarer than hydride shift but yes as keshav said
one sec sharing example (happen to be working on a q that had it :)
Basically, as far as ik, the carbocation rearrange itself to become more stable
nest ka sawal tha ye 2023 ka
6 membered more stable than 5 membered. so it is very reaction dependent
usually hyrdide shift is more common
(not pirating stuff)
You can read section 6.7 in py bruice
Ah tertiary carbon is more stable so it rearranges itself? Is that what methyl shift is?
In E1 elimination rxn
Thanks sir, but how was the 2nd ring formed?
the pi electrons from benzene attack the positive charge
rxn mechanism me dala hai
(the green arrows show the movement of electrons. the arrows start at the electrn rich species, and end at the electron deficient species - i.e. the empty, unhyb p orbital)
Ahh got it Sir dhanyavad 🙏
