Question

Which of the following complex exhibits geometrical isomerism?

• A. $\left[Zn\right(gly{)}_2]$
• B. $\left[Cu\right(en\left)\right(N{H}_3{)}_2{]}^{+}$
• C. $\left[PtBrCl\right(N{H}_3\left)\right(py\left)\right]$
• D. $\left[Ni\right(CN{)}_2(CO{)}_2{]}^{2-}$

Answer 1

The correct option is C $\left[PtBrCl\right(N{H}_3\left)\right(py\left)\right]$

$\left[PtBrClN{H}_{3}Py\right],P{t}^{2+}\text{is}ds{p}^2$ hybridised & hence geometry is square planar & square planar complex with four different ligands shows geometrical isomerism.
