Which among following is a strongest base?
- A Benzenamine
- B Phenylmethanamine
- C N, N-Dimethylbenzenamine
- D N-Methylbenzenamine
Answer & Solution
Correct Answer
(B) Phenylmethanamine
Step-by-step Solution
Detailed explanation
In arylamines, the \(-\mathrm{NH}_2\) group is attached directly to an aromatic ring. The lone pair of electrons on nitrogen is conjugated to the aromatic ring and is less available for protonation. In phenylmethanamine (aliphatic amine), lone pair of electrons on nitrogen is available for protonation. Hence, phenylmethanamine is the strongest base among the given amines.
