Question

Which of the following is true about the complex $\left[PtC{l}_2\right(H_{2}O\left)\right(N{H}_3\left)\right]$?

• A. It exhibits geometrical isomerism
• B. It is paramagnetic complex
• C. Its geometry is tetrahedron
• D. Platinum is $s{p}^3$ hybridised

Answer 1

The correct option is A It exhibits geometrical isomerism

The complex $\left[PtC{l}_2\right(H_{2}O\left)\right(N{H}_3\left)\right]$ exhibits geometrical isomerism in the form of cis and trans isomers.

The oxidation state of platinum is +2 its outer electronic configuration is $5d^8$.Pt undergoes $ds{p}^2$ hybridization which results in square planar geometry.

All electrons are paired and the molecule is diamagnetic in nature.

Hence, the correct option is A.
