The reagent(s) which can be used to distinguish acetophenone from benzophenone is (are)

1. 2,4-Dinitrophenylhydrazine
2. Aqueous solution of NaHSO3
3. Benedict reagent
4. I2 and NaOH

Correct answer: Aqueous solution of NaHSO3

Solution

Acetophenone reacts with aqueous NaHSO3 to form a bisulfite addition compound due to the presence of a methyl ketone group, while benzophenone does not react. This distinguishes the two compounds.
