Text Solution

Verified by Experts

The correct Answer is:
A, B, C
(a,b,c)
A `3^@` alcohol containing three identical alkyl groups (the values of `R` obtained from `G.R`) may be obtained from `G.R`) may be prepared by the reaction between `3 mol` of `G.R`. `(PhMgBr)` with `1 mol` of ethyl carbonate.

But benzamide gives ketone :
