Question

Identify A in the following chemical reaction.

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

The explanation for the correct option:

1st reaction will be the Cannizaro reaction: It is a chemical reaction named after Stanislao Cannizzaro that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to yield a carboxylic acid and a primary alcohol.

2nd reaction is with reagents ethyl bromide (${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{Br}$), sodium hydride ($\mathrm{NaH}$), N, N-Dimethylformamide ($\mathrm{DMF}$) will form p-ethoxymethyl anisole from 4-methoxy benzyl alcohol.

3rd reaction is a decomposition reaction with the reagent hydrogen iodide ($\mathrm{HI}$) and the final product will be formed.

The possible chemical process for the given problem is shown below:

Hence, option (C) is the correct answer.
