Question

Ammonia is less basic than aniline.

1. What is the reason for low basic character of aniline compared to ammonia?

2. Draw the resonating structures of aniline

Answer 1

1. In aromatic amines the lone pair on nitrogen is in conjugation with benzene ring due to resonance effect and thus making it less available for protonation. Hence basic character is less than that of ammonia.
