What happens when acetophenone reacts with sodium hypochlorite?

The correct answer is option 2. Sodium benzoate + chloroform.

When acetophenone reacts with sodium hypochlorite, it undergoes a haloform reaction. Sodium hypochlorite (NaOCl) provides the halogen (chlorine in this case) needed for this reaction.

In the haloform reaction, a methyl ketone (a compound with the structure \(R-CO-CH_3\)) reacts with a halogen (chlorine in this case) and a base to produce a carboxylate ion and a haloform (in this case, chloroform).


Acetophenone \((C_6H_5COCH_3)\) reacts with sodium hypochlorite to produce sodium benzoate \((C_6H_5COONa)\) and chloroform \((CHCl_3)\).

So, the correct answer is: Sodium benzoate + chloroform.
