$II, III$

Vedclass · Answer

(C) molecule is chiral if it lacks a plane of symmetry or center of inversion. $(I)$ $1,3$-dimethylcyclobutane (trans-isomer) has a center of inversion,so it is achiral. $(II)$ $1$-chloro-$2,3$-dimethylcyclobutane has no plane of symmetry or center of inversion,so it is chiral. $(III)$ $1,2$-dimethylcyclobutane (trans-isomer) has a $C_2$ axis of symmetry but no plane of symmetry or center of inversion,so it is chiral. $(IV)$ $1,2,3,4$-tetramethylcyclobutane (all-trans isomer) has a center of inversion,so it is achiral. Thus,$(II)$ and $(III)$ are chiral.
