Question

Canonical structure of anilinium ion obtained by accepting a proton are given below. Choose the correct statements.

• A. Anilinium ion has two stable canonical structures I and III.
• B. II is not an acceptable structure because carbonium ion is less stable.
• C. Only I and III are acceptable aromatic canonical structures since II is non - aromatic.
• D. Anilinium ion has three stable canonical structure I, II and III.

Answer 1

Answer: (A)

Anilinium ion has two stable canonical structures I and III.

II is not an acceptable canonical structure because nitrogen has 10 valence electrons in the structure. Anilinium ion exists in two canonical structures only which are I and III.
