Questions: 6 | Attempts: 2266 | Last updated: Mar 22, 2023

Sample Question
Why is there a huge gain in the stability of benzene's double bonds compared to cyclohexene?

Cyclic congugation increases the number of p orbital interactions in the conjugated system, stabilizing the pi bonds. Cyclohexene lacks this stability, and the energy of its pi bond is greater (less stable).

The linear conjugation of the cyclohexene makes it less stable.

Cyclic congugation increases the number of p orbital interactions in the conjugated system, stabilizing the pi bonds. Cyclohexene has only linear delocalized pi electrons.
