Sample Question
What are Aromatic Hydrocarbons?

Hydrocarbons that are only used in industrial solvents.

Hydrocarbons that are exclusively found in non-aromatic plants.

Those which contain one or more benzene rings. The name of the class come from the fact that many of them have strong, pungent aromas

Hydrocarbons that do not contain any benzene rings.

Aromaticity

Questions: 6 | Attempts: 2387 | Last updated: Mar 22, 2025

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.
