Compare heat of hydrogenation of the following
Options
- AI > I I > I I I
- BI I I > I I > I
- CI I > I I I > I
- DI I > I > I I I
Correct answer
B. I I I > I I > I
Step-by-step solution
For isomeric alkene Heat of hydrogenation ∝ 1 Stabilities of alkene More the number of α - hydrogen atoms, more is the stability of alkene and less is the heat of hydrogenation value.
