Among the following. The set which represents aromatic species is

Options

  1. AI, II and III
  2. BIII, IV and V
  3. CII and III
  4. DI, II and IV

Correct answer

D. I, II and IV

Step-by-step solution

Compounds I, II and IV have continuous delocalisation of -electrons and have (4 n+2 ) electrons. On the other hand compound III does not shows conjugation and compound V has 4 n electrons. Thus, compounds given in only I, II and IV are aromatic.
