Consider the following isomerization process:

What can be predicted accurately for this process?

A

The process is exothermic

B

Enthalpy change of reaction `(Delta_r H^@)` Resonance enthalpy of product

C

enthalpy of combustion `(Delta_C H^@)` of product is less than that of reactant

D

Combustion of the reactant will be exothermic while the same of products will be endothermic

Text Solution

Verified by Experts

The correct Answer is:
A, C
(A) Process is exothermic as the product is stable (lower in energy due to conjugation) than the reactant
(C) Enthalpy of combustion of product is lesser than the reactant as the former is more stable.
(D) Combustion of any hydrocarbon is always exothermic
