Vedclass · Answer

(C) The stability of an alkene is directly proportional to the number of $\alpha$-hydrogen atoms attached to the double-bonded carbon atoms (hyperconjugation effect).$1$. $(CH_3)_3C-CH=CH_2$: The double-bonded carbons have $0$ $\alpha$-hydrogen atoms.$2$. $CH_2=CH_2$: This has $0$ $\alpha$-hydrogen atoms.$3$. $(CH_3)_2C=CH_2$: The double-bonded carbon has two methyl groups attached,providing $6$ $\alpha$-hydrogen atoms.$4$. $CH_3-CH=CH_2$: This has $3$ $\alpha$-hydrogen atoms.Since $(CH_3)_2C=CH_2$ has the highest number of $\alpha$-hydrogen atoms $(6)$,it is the most stable alkene among the given options.
