The reagent which can be used to distinguish acetopheone from benzophenone is :

A

2, 4-Dinitrophenone hydrazine

B

Benedict solution

C

Tollen's reagent

D

`I_(2)` and `Na_(2)CO_(3)`.

Text Solution

Verified by Experts

The correct Answer is:
D
Acetophenone `(C_(6)H_(5)COCH_(3))` will form a yellow ppt. with `I_(2)` and `Na_(2)CO_(3)` while benzophenone `(C_(6)H_(5)COC_(6)H_(5))` will not react because of ore steric hindrance.
