उत्तर

The reagent that can be used to distinguish acetophenone and benzophenone is I2 and NaOH.

Explanation:

In the preceding test, the I2 and NaOH tests are utilized to differentiate between acetophenone and benzophenone. When iodine molecules react with acetophenone, they generate methyl iodide by combining with methyl groups. The synthesis of methyl iodide produces a yellow precipitate, indicating that the molecule is acetophenone.

However, no precipitate is generated when I2 and NaOH combine with benzophenone. Because benzophenone has a ring that resists precipitation, this reaction does not occur.
