Q37Multiple choice
The ring systems having following characteristics are aromatic.
- (i)Planar ring containing conjugated π bonds.
- (ii)Complete delocalisation of the π−electrons in ring system i.e. each atom in the ring has unhybridised p-orbital, and
- (iii)Presence of (4n+2) π−electrons in the ring where n is an integer (n = 0, 1, 2,...........) [Huckel rule]. Using this information classify the following compounds as aromatic/nonaromatic.
