The following compound has a high dipole moment. The main reason is :
Options:
Answer:
B
Solution:
The exocyclic C=C polarises so that the five-membered ring carries a negative charge (cyclopentadienyl anion, 6 π electrons) and the three-membered ring carries a positive charge (cyclopropenyl cation, 2 π electrons). Both rings gain aromatic stability, so this dipolar structure contributes strongly and the dipole moment is high.
