Vedclass · Answer

(C) The $E2$ elimination requires an anti-periplanar arrangement of the leaving group $(Cl)$ and the $\beta$-hydrogen. In the chair conformation,the bulky isopropyl group prefers the equatorial position. Elimination can occur from two $\beta$-carbons,leading to two possible products,$(I)$ and $(II)$. Product $(II)$ has $5$ $\alpha$-hydrogens,making it more substituted and thus more stable than product $(I)$. Therefore,$(II)$ is the major product,which is $4$-isopropyl-$1$-methylcyclohex-$1$-ene.
