Question

Azulene  has dipole moment 0.8 D because

  1. It exists as aromatic compound in which both the rings are aromatic    
  2. Charge separation permits conformational stability    
  3. The two rings are of different size    
  4. The molecules obey (4n + 2) Huckel rule    

The correct answer is: It exists as aromatic compound in which both the rings are aromatic
