Step 1: Polar Resonance in Fulvalenes
Some non-polar looking hydrocarbons exhibit high dipole moments due to zwitterionic aromatic resonance.
- Structure (a) (Triapentafulvalene): The double bond between the 3-membered and 5-membered rings can polarize to create a -electron cyclopropenyl cation (Aromatic) and a -electron cyclopentadienyl anion (Aromatic).

Step 2: Conclusion
This double aromaticity stabilization makes the zwitterionic form highly likely, leading to a very high dipole moment.
