An organic compound "A" reacts with \(\mathrm{Zn} / \mathrm{Hg} /\) Conc. HCl to form p-Xylene. It reduces Tollen's reagent and on oxidation with \(\mathrm{KMnO}_4 / \mathrm{H}^{+}\)it yields 1, 4-benzenedicarboxylic acid.
Identify compound A .
- A m- Cresol.
- B 4-Methylacetophenone.
- C p-methylbenzaldehyde.
- D p- Cresol.
Answer & Solution
Correct Answer
(C) p-methylbenzaldehyde.
Step-by-step Solution
Detailed explanation
The compound A reacts with \(\mathrm{Zn/Hg/Conc. HCl}\) (Clemmensen reduction) to form p-Xylene. This indicates that the carbonyl group of an aldehyde or ketone is reduced to a methylene group. The structure of p-Xylene is \(1,4\)-dimethylbenzene. The compound A reduces Tollen's…
