Diphenylcyclopropenone

Vedclass · Answer

(C) The dipole moment of a molecule depends on the separation of charge. In $Diphenylcyclopropenone$,the carbonyl group $(C=O)$ can undergo polarization such that the oxygen atom acquires a negative charge and the three-membered ring acquires a positive charge. The resulting structure has a $2\pi$ electron system in the ring,which makes it aromatic according to $H$ückel's rule ($4n+2$ electrons,where $n=0$). Because this resonance-stabilized structure is highly stable,the molecule exhibits a very high degree of charge separation,leading to a maximum dipole moment compared to the other options.

Which of the following has the maximum dipole moment?
