Open in App

Solution

Total seven complexes will show cis-trans isomerism.
$(i) [C o (N H_{3})_{4} (H_{2} O) C l]^{2 +}$

$(i i) [P t (N H_{3})_{2} C l_{2}]$

$(i i i) [C o C l_{2} (e n)_{2}]^{+}$

$(v) [F e (N H_{3})_{2} (C N)_{4}]^{-}$

$(v i) [C r C l_{2} (o x)_{2}]^{3 -}$

$(v i i) K [C o (H_{2} O)_{2} (o x)_{2}]$

$(v i i i) [C o (N H_{3})_{2} C l_{2} (e n)]^{+}$

$(i v) [C r (H_{2} O)_{5} C l] C l_{2}$ will show solvate isomerism and $(i x) [C o (e n)_{3}] C l_{3}$ will show optical isomerism.
