Question
Chapter 8.3, Problem 4P
Interpretation Introduction
Interpretation:
Each of the given alkene is to be matched with its correct heat of hydrogenation.
Concept introduction:
Heat that is given off in the catalytic hydrogenation of an alkene is known as the heat of hydrogenation.
The more substituted the double bond, the more stable is the alkene.
A tri substituted double bond is the most stable and has the lowest heat of hydrogenation.
A mono substituted double bond is the least stable and has the highest heat of hydrogenation.
