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

Options

  1. AAnilinium ion has two stable canonical structures I and III
  2. BII is not an acceptable structure because carbonium ion is less stable
  3. COnly I and III are acceptable aromatic canonical structures since II is non-aromatic
  4. DAnilinium ion has three stable canonical structures I, II and III

Correct answer

A. Anilinium ion has two stable canonical structures I and III

Step-by-step solution

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.
