$(a)$ $cis-[CrCl_{2}(ox)_{2}]^{3-}$

Vedclass · Answer

(A) coordination entity is chiral if it lacks a plane of symmetry and a center of inversion.$(a)$ The $cis-[CrCl_{2}(ox)_{2}]^{3-}$ isomer lacks both a plane of symmetry and a center of inversion,making it chiral (optically active).$(b)$ The $trans-[CrCl_{2}(ox)_{2}]^{3-}$ isomer possesses a plane of symmetry (and a center of inversion),making it achiral (optically inactive).Therefore,the $cis$ isomer is the chiral one.

Out of the following two coordination entities,which is chiral (optically active)?
$(a)$ $cis-[CrCl_{2}(ox)_{2}]^{3-}$
$(b)$ $trans-[CrCl_{2}(ox)_{2}]^{3-}$
