A)
B)
C)
D)
Correct Answer: A
Solution :
Heat of hydrogenation of alkene\[\propto \frac{\text{1}}{\text{Stability}\,\text{of}\,\text{alkene}}\] Hence the alkene which will react fastest with \[{{H}_{2}}\]will be the least stable. Among the given options the compound having least number of alkyl groups (R) will be the least stable. Further the relative rates of hydrogenation decrease with increase of steric hindrance Hencewill react fast with \[{{H}_{2}}.\]You need to login to perform this action.
