(a)
Interpretation:
Most stable
Concept introduction:
The amount of heat released in a hydrogenation reaction is known as heat of hydrogenation
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
The stability of an alkene increases as the number of hydrogen bonded to its
(b)
Interpretation:
Least stable alkene has to be identified.
Concept introduction:
The amount of heat released in a hydrogenation reaction is known as heat of hydrogenation
