Question

Which of the following complex can not exhibit geometrical isomerism :

• A. $\left[Pt{\left(N{H}_3\right)}_{2}ClN{O}_2\right]$
• B. $\left[Pt{\left(gly\right)}_2\right]$
• C. ${\left[Cu{\left(en\right)}_2\right]}^{+}$
• D. $\left[Pt\left(H_{2}O\right)\left(N{H}_3\right)BrCl\right]$

Answer 1

The correct option is C ${\left[Cu{\left(en\right)}_2\right]}^{+}$

Option (C) is correct.

${\left[Cu{\left(en\right)}_2\right]}^{+}$ complex can not exhibit geometrical isomerism because $en$ is bidentate ligand.
