$1,4-$dimethylcyclohexane

Vedclass · Answer

(C) molecule is achiral if it possesses a plane of symmetry or a center of inversion. $(a)$ $2$-bromocyclohexanol has chiral centers and no plane of symmetry,so it is chiral. $(b)$ $2$-chlorohexane has a chiral carbon at the $C2$ position,so it is chiral. $(c)$ $1,4$-dimethylcyclohexane (specifically the cis-isomer) has a plane of symmetry passing through $C1$ and $C4$,making it achiral. $(d)$ $1$-chloro-$2$-deuterocyclohexane has chiral centers and no plane of symmetry,so it is chiral. Therefore,the correct option is $C$.
