Vedclass · Answer

(C) The stability of an alkene is directly proportional to the number of alkyl groups attached to the doubly bonded carbon atoms (hyperconjugation effect). Let us analyze the number of alpha-hydrogens for each option: $A$) $2$-methylprop-$1$-ene: $6$ $\alpha$-hydrogens. $B$) $2$-methylbut-$2$-ene: $9$ $\alpha$-hydrogens. $C$) $2,3$-dimethylbut-$2$-ene: $12$ $\alpha$-hydrogens. $D$) trans-but-$2$-ene: $6$ $\alpha$-hydrogens. Since $2,3$-dimethylbut-$2$-ene has the highest number of $\alpha$-hydrogens $(12)$,it is the most stable alkene among the given options.
