Chapter 12.3, Problem 2P

Interpretation Introduction

Interpretation:

The resonance energy of $\text{1,3,5-cycloheptatriene}$ is to be determined and the resonance energy of $\text{1,3,5-cycloheptatriene}$ is to be compared with the resonance energy of benzene.

Concept Introduction:

>

Heat of hydrogenation can be used to compare the stabilities of unsaturated compounds.

>

The difference between heat of hydrogenation of $\text{1,3,5-cycloheptatriene}$ is estimated on the basis of heat of hydrogenation of $\text{cycloheptene}$, and the measured heat of hydrogenation is due to resonance stabilization.
