C

i and iii

D

ii and iii

Text Solution

Verified by Experts

The correct Answer is:
B
The reactivity of the carbonyl group towards addition reaction depends upon the magnitude of the positive charge on the carbonyl carbon atom.Hence, any substituent that increases the`+ve` chargeon the carbonyl carbon must increase its reactivity group ( -Ieffect) increases the reactivity while introduction of alkyl group `(+I` effect ) decreases the reactivity.
Large and bulky group creates hindrance in approach towards carbonyl carbon. So,large alkyl group decreases the reactivity of `gt C =O`group.
