The reagent(s) which can be used to distinguish acetophenone from benzophenone is (are):
Show Hint
- 2,4-dinitrophenylhydrazine
- aqueous sodium bisulphite
- Benedict reagent
- I₂ and NaOH
The Correct Option is D
Solution and Explanation
Step 1: Iodoform test. Acetophenone gives positive iodoform test.
Step 2: Benzophenone behaviour. Benzophenone does not respond to iodoform test.
