Question

What is 'Z' in the given sequence of reactions?

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Reduction of aromatic aldehydes with hydrogenation or the use of reagents like Zn-Hg can convert the aldehyde group into a methyl group.

Answer 1

The Correct Option is B

The given reaction involves oxidation with KMnO4, followed by hydrogenation, and finally, the reaction with Zn and Hg in the presence of conc. HCl. This sequence converts a benzaldehyde (CHO) group into a methyl group (CH3) through these reduction steps.
