Given :

The enthalpy of hydrogenation of these compounds will be in the order as :

A

II gt III gt I

B

II gt I gt III

C

I gt II gt III

D

III gt II gt I

Text Solution

Verified by Experts

The correct Answer is:
D
`"Enthalpy of hydrogenation" prop (1)/("stability of alkene")`
`"Stability order : "I gt II gt III`
So enthalpy of hydrogenation is `I lt II lt III`
