Suppose the complex ion $[C o (N H_{3})_{2} (H_{2} O)_{2} C l_{2}]^{-}$ is synthesized with two ammine ligands $c i s$ to each other, the two aqua ligands $c i s$ to each other and two chloro ligands $c i s$ to each other. Is this complex optically active?

Open in App

Solution

Mirror images are nonsuper-impossible hence the complex is optically active (being chiral).
