Vedclass · Answer

(A) The hyperconjugation effect depends on the number of $\alpha$-hydrogen atoms available on the carbon atom adjacent to the double bond.$1$. For $CH_3-CH=CH_2$,the number of $\alpha$-hydrogens is $3$.$2$. For $CH_3CH_2-CH=CH_2$,the number of $\alpha$-hydrogens is $2$.$3$. For $(CH_3)_2CH-CH=CH_2$,the number of $\alpha$-hydrogens is $1$.Since the hyperconjugation effect is directly proportional to the number of $\alpha$-hydrogen atoms,the order is $CH_3- > CH_3CH_2- > (CH_3)_2CH-$.

For the compound $R-CH=CH_2$,what is the order of the hyperconjugation effect for the group $R$,where $R$ is $CH_3-$,$CH_3CH_2-$,or $(CH_3)_2CH-$?
