Question

The product B is

• A. N, N-Dimethyl phenyl methanamine
• B. N, N-Dimethyl benzenamine
• C. N-Benzyl-N-methyl methanamine
• D. phynyl-N-N-dimethyl methanamine

Answer 1

The Correct Option is A

Let's analyze the reaction step by step:

The starting compound is benzyl chloride (C₆H₅CH₂Cl), which contains a benzyl group (C₆H₅CH₂-) attached to a chlorine atom.

The reaction with alcoholic NH₃ (ammonia) leads to a nucleophilic substitution where ammonia replaces the chlorine atom to form benzylamine (C₆H₅CH₂NH₂). This is the product A.

In the second step, the reaction with excess CH₃Cl (methyl chloride) results in the methylation of the amine group, leading to N, N-dimethylphenylmethanamine (C₆H₅CH₂NH(CH₃)₂). This is the product B.
 

The correct answer is (A) : N, N-Dimethyl phenyl methanamine.
