Assertion:In the presence of alkaline KMnO4 4- methylacetophenone is oxidised to benzoic acid. Reason :Keto group is oxidised to —COOH group. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

Alkaline KMnO4 will oxidise both, -CH3 and -COCH3 groups to -COOH group. Hence benzene- 1,4- dicarboxylic acid (terephthalic acid) will be formed.

Q. Assertion:In the presence of alkaline $K M n O_{4} 4 -$ methylacetophenone is oxidised to benzoic acid.
Reason :Keto group is oxidised to $— COO H$ group.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Alkaline $K M n O_{4}$ will oxidise both, $- C H_{3}$ and $- COC H_{3}$ groups to $- COO H$ group. Hence benzene- $1, 4 -$ dicarboxylic acid (terephthalic acid) will be formed.
