Question

The inner orbital complex which exhibits both geometrical as well as optical isomerism.

• A. $\left[Cr\right(en{)}_3{]}^{3+}$
• B. $\left[Ir{F}_3\right(H_{2}O{)}_2\left(N{H}_3\right)]$
• C. $\left[NiC{l}_2\right(en{)}_2]$
• D. $\left[Co\right(CN{)}_2(ox{)}_2{]}^{3-}$

Answer 1

Answer: (C), (D)

The correct options are
C $\left[NiC{l}_2\right(en{)}_2]$
D $\left[Co\right(CN{)}_2(ox{)}_2{]}^{3-}$

$\left[Cr\right(en{)}_3{]}^{3+};Hyb,:d^{2}s{p}^3$; does not exhibit geometrical isomerism but exhibits optical isomerism.

$\left[Ir{f}_3\right(H_{2}O\left(N{H}_3\right)];Hyb.:d^{2}s{p}^3$; exhibits geometrical isomerism but does not exhibit optical isomerism.

$\left[NiC{l}_2\right(en{)}_2];Hyd.:s{p}^3{d}^2$; exhibits both geometrical isomerism and optical isomerism.

$\left[Co\right(CN{)}_3(ox{)}_2{]}^{3-};Hyb.:d^{2}s{p}^3$; exhibits both geometrical isomerism and optical isomerism.
