Which of the following is highly basic?

Options

  1. ADiphenylamine
  2. BBenzylamine
  3. CAniline
  4. DTriphenylamine

Correct answer

B. Benzylamine

Step-by-step solution

The basicity of amines is determined by the availability of the lone pair of electrons on the nitrogen atom for protonation. In aniline, the lone pair on the nitrogen atom is involved in resonance with the benzene ring, which decreases its availability for protonation, making it weakly basic. In diphenylamine, the lone pair on the nitrogen atom is involved in resonance with two benzene rings, which further decreases its availability compared to aniline, making it even less basic. In triphenylamine, the lone pair on
