Question

An organic compound "A" reacts with \( \text{Zn}/\text{Hg} / \text{Conc. HCl} \) to form p-Xylene. It reduces Tollen's reagent and on oxidation with \( \text{KMnO}_4 / H^+ \) it yields 1,4-benzenedicarboxylic acid. Identify compound A.

• A. \( \text{p-methylbenzaldehyde} \)
• B. \( \text{p-Cresol} \)
• C. \( \text{m-Cresol} \)
• D. \( 4 \)-Methylacetophenone

Hint:

The Clemmensen reduction reduces an aldehyde to a methyl group, and Tollen's reagent can be used to identify aldehydes. Oxidation with \( \text{KMnO}_4 \) leads to the formation of carboxylic acids.

Answer 1

The Correct Option is A
