Question

Determine the correct order of hybridization of the central atom in the following species $NH_{3}$ , $\left[\right.PtCl_{4}\left]\right.^{2 -},PCl_{5}$ and $BCl_{3}$ .

• A. $dsp^{2},dsp^{3},sp^{2}$ and $sp^{3}$
• B. $sp^{3},dsp^{2},dsp^{3},sp^{2}$
• C. $dsp^{2},sp^{2},sp^{3},dsp^{3}$
• D. $dsp^{2},sp^{3},sp^{2},dsp^{3}$

Answer 1

Answer: (B)

Hybridization of N in $NH_{3}$ is $sp^{3}$ that of Pt in $\left[\right.PtCl_{4}\left]\right.^{2 -}$ is $dsp^{2}$ that P in $PCl_{5}$ is $sp^{3}d$ and that of B in $BCl_{3}$ is $sp^{2}$ .
