Vedclass · Answer

(D) molecule is achiral if it possesses a plane of symmetry,a center of inversion,or an improper axis of rotation. $(A)$ The first compound (a bicyclic anhydride) has a plane of symmetry passing through the anhydride ring and bisecting the bicyclic system. Thus,it is achiral. $(B)$ The second compound (a bicyclic hydrocarbon) also possesses a plane of symmetry,making it achiral. $(C)$ The third compound (a substituted bicyclo[$2.2$.$1$]heptane) has a plane of symmetry passing through the $C-Br$ bond and the bridgehead carbon,making it achiral. Since all the given compounds possess a plane of symmetry,they are all achiral. Therefore,the correct option is $D$.
