Vedclass · Answer

(D) Optical activity in coordination compounds requires the absence of a plane of symmetry or center of inversion. $1$. $[Co(en)_3]^{3+}$ is a chiral complex and is optically active. $2$. $[Cr(Ox)_3]^{3-}$ is a chiral complex and is optically active. $3$. $cis-[CoCl_2(en)_2]^+$ lacks a plane of symmetry and is optically active. $4$. $trans-[CoCl_2(en)_2]^+$ possesses a plane of symmetry (the plane containing the $Co$ atom and the two $Cl$ atoms),making it achiral and optically inactive.

Which of the following is not optically active?
