Vedclass · Answer

(C) The heat of hydrogenation is inversely proportional to the stability of the alkene. More substituted alkenes are more stable due to hyperconjugation and inductive effects. $1$. $CH_3-CH=CH-CH_3$ ($2$-butene) is a disubstituted alkene. $2$. $CH_3-CH=CH-C_2H_5$ ($2$-pentene) is a disubstituted alkene. $3$. $C_2H_5-CH=CH_2$ ($1$-butene) is a monosubstituted alkene. $4$. $C_2H_5-CH=CH-C_2H_5$ ($3$-hexene) is a disubstituted alkene. Since monosubstituted alkenes are less stable than disubstituted alkenes,$C_2H_5-CH=CH_2$ has the lowest stability and therefore the maximum heat of hydrogenation.
