Question

The correct order of hybridisation of the central atom in the following species : $N{H}_3,[PtC{l}_4{]}^{2-},PC{l}_5$ and $BC{l}_3$ is

• A. $ds{p}^2,ds{p}^3,s{p}^2,s{p}^3$
• B. $s{p}^3,ds{p}^2,ds{p}^3,s{p}^2$
• C. $ds{p}^2,s{p}^2,s{p}^3,ds{p}^3$
• D. $ds{p}^2,s{p}^3,s{p}^2,s{p}^3$

Answer 1

Answer: (B)

$s{p}^3,ds{p}^2,ds{p}^3,s{p}^2$

The correct order of hybridisation of the central atom in the following species : $N{H}_3,[PtC{l}_4{]}^{2-},PC{l}_5$ and $BC{l}_3$ is $s{p}^3,ds{p}^2,ds{p}^3,s{p}^2$ respectively. The corresponding geometries are pyramidal, square planar, trigonal bipyramidal and trigonal planar respectively.
