C

`CH_(3)-underset(underset(CH_(3))|)(C)H_(2)-CHO" "&" "CH_(3)-overset(overset(Br)|)(C)H-underset(underset(Cl)|)(C)H-CHO`

D

`CH_(3)-CH=CH-overset(overset(OH)|)(C)H-CH_(3)" "&" "CH_(3)-overset(overset(Cl)|)(C)H-underset(underset(Br)|)(C)H-CHO`

Text Solution

Verified by Experts

The correct Answer is:
4
P is formed by `1,2` addition which is a nucleophilic addition while Q is formed by electrophilic addition to the `gt C=Clt` following a more stable intermediate.
