azulene

Vedclass · Answer

(D) The correct answer is $(D)$.Azulene is a non-benzenoid aromatic hydrocarbon consisting of a five-membered ring fused to a seven-membered ring.Due to the electron transfer from the seven-membered ring to the five-membered ring,the molecule acquires a dipolar structure where the five-membered ring becomes negatively charged (aromatic $6\pi$-electron system) and the seven-membered ring becomes positively charged (aromatic $6\pi$-electron system).This significant charge separation results in a high dipole moment of approximately $1.0 \ D$.In contrast,naphthalene,anthracene,and phenanthrene are benzenoid hydrocarbons with zero or negligible dipole moments due to their symmetric structures.

Which compound possesses the highest dipole moment?
