(a)

Interpretation Introduction

Interpretation:

More stable alkene should be identified from the given alkenes.

Concept introduction:

The amount of heat released in a hydrogenation reaction is known as heat of hydrogenation(ΔH0).

The most stable alkene has the smallest heat of hydrogenation.

The stability of an alkene increases as the number of alkyl substituents bonded to its sp2 carbon increases.

The stability of an alkene increases as the number of hydrogen bonded to its sp2 carbon decreases.
