Question

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

• A. $ds{p}^2,ds{p}^3,s{p}^2$ and $s{p}^3$
• 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. $ds{p}^2,s{p}^3,s{p}^2,ds{p}^3$

Answer 1

Answer: (B)

Hybridization of N in $N{H}_3$ is $s{p}^3$ that of Pt in $[PtC{l}_4{]}^{2-}$ is $ds{p}^2$ that P in $PC{l}_5$ is $s{p}^{3}d$ and that of B in $BC{l}_3$ is $s{p}^2$ .
