Enthalpy of hydrogenation of benzene is ...

Enthalpy of hydrogenation of benzene is `DeltaH_(1)` and for cyclohexene is `DeltaH_(2)`. The resonance energy of benzene is

A

`3DeltaH_(1) - DeltaH_(2)`

B

`3DeltaH_(2)-DeltaH_(1)`

C

`3DeltaH_(1) +DeltaH_(2)`

D

`DeltaH_(1) -3DeltaH_(2)`

Text Solution

Verified by Experts

Heat of hydrogenation is always negative and benzene is more stable than cyclohexatriene. Therefore, resonance enegy should be negative.
`:. 3DeltaH_(2) - DeltaH_(1)`
