Question

N-alkyl aniline is the product of:

• A. nitration of benzene
• B. alkylation of aniline
• C. acylation of aniline
• D. benzoylation of aniline

Answer 1

Answer: (B)

alkylation of aniline

N-alkyl aniline is the product of alkylation of aniline.
When aniline is treated with alkyl halide, N-alkyl aniline is obtained. However, N-alkyl aniline reacts further with another molecule of alkyl halide to form N,N-dialkyl aniline. N,N-dialkyl aniline further reacts with another molecule of alkyl halide to form trialkylanilinium halide, which is a quaternary ammonium salt.
