hyperconjugative effect of the $Me$ groups

Vedclass · Answer

(C) The stability of alkenes is determined by the number of hyperconjugative structures, which depends on the number of $\alpha$-hydrogen atoms attached to the $sp^2$ hybridized carbon atoms.In $Me_2C=CH_2$ ($2$-methylprop$-1-$ene), there are two $Me$ groups attached to the double-bonded carbon, providing $3 + 3 = 6$ $\alpha$-hydrogen atoms.In $MeCH_2CH=CH_2$ (but$-1-$ene), there is only one $MeCH_2$ group attached to the double-bonded carbon, providing $2$ $\alpha$-hydrogen atoms.Since $Me_2C=CH_2$ has more $\alpha$-hydrogen atoms $(6)$ compared to $MeCH_2CH=CH_2$ $(2)$, it exhibits a greater hyperconjugative effect, making it more stable.

The stability of $Me_2C=CH_2$ is more than that of $MeCH_2CH=CH_2$ due to
