Question

b) Give the major product formed by the following S1 substitution reactions: (8 points) Me NH H Da HO e heat OH c) Give the major product formed by the following Syl substitution reaction and the mechanism for its formation: (9 points) te chot CH₂OH,

Answer 1

b) In SN1 reaction, carbocation is formed. In these two reaction, rearrangement takes place to give more stable carbocation.

i) Product is :

H3C, CH3 H₃C CS Searned with

ii) Product is :

cs Scanned with CamScanner

c) In this reaction, Br remove with it's electron and form carbocation which undergo ring expansion followed by Nucleophilic attack of CH3OH.
