Examine the following two structures for the anilinium ion and choose the correct statement from the ones given below

Options

  1. AII is not an acceptable canonical structure, because carbonium ions are less stable than ammonium ions
  2. BII is not an acceptable canonical structure, because it is non-aromatic
  3. CII is not an acceptable canonical structure, because the nitrogen has 10 valence electrons
  4. DII is an acceptable canonical structure

Correct answer

C. II is not an acceptable canonical structure, because the nitrogen has 10 valence electrons

Step-by-step solution

II is not acceptable canonical form, because the nitrogen atom has 10 valence electron. Since N does not have d-orbitals in its valence shell, therefore, its octet cannot be expanded.
