Question

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

विकल्प

• 2, 4-dinitrophenyl hydrazine

• aqueous NaHSO₃

• Fehling solution

• I₂ and NaOH

Answer 1

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.
