Vedclass · Answer

(D) For a molecule to be optically active,it must lack a plane of symmetry $(P.O.S.)$ and a center of symmetry $(C.O.S.)$.$A$: This is a substituted allene with an odd number of double bonds. The terminal groups are in the same plane,and it possesses a plane of symmetry. Thus,it is optically inactive.$B$: This is a bicyclic compound with a plane of symmetry passing through the molecule. Thus,it is optically inactive.$C$: This is $cis-1,3-dimethylcyclopentane$. It has a plane of symmetry passing through the $C_2$ and $C_5$ atoms. Thus,it is optically inactive.$D$: This is a tartaric acid derivative. In the given configuration,there is no plane of symmetry or center of symmetry. Therefore,it is chiral and optically active.
