Vedclass · Answer

(A) The rate of catalytic hydrogenation of alkenes depends on the stability of the alkene. More substituted alkenes are more stable and have lower heat of hydrogenation,thus they react slower. Less substituted alkenes are less stable and have higher heat of hydrogenation,thus they react faster. Comparing the given structures: $A$: $CH_3-CH_2-CH=CH_2$ (monosubstituted) $B$: $CH_3-CH=CH-CH_3$ (disubstituted,cis) $C$: $CH_3-CH=CH-CH_3$ (disubstituted,trans) $D$: $(CH_3)_2C=CH_2$ (disubstituted) Among these,the monosubstituted alkene $(A)$ is the least stable and therefore undergoes hydrogenation at the fastest rate.

Which of the following undergoes reduction (by $H_2|Ni$) at the fastest rate?
