Question:

$\text{Match the compounds given in Column-I with their respective}$ $\text{hybridisation which is given in Column-II.}$ $\begin{array}{|c|c|} \hline \text{Column-I (Compound)} & \text{Column-II Hybridisation} \\ \hline (i) \ \text{PCl}_5 & (a) \ sp^3d^2 \\ (ii) \ [\text{Pt(CN)}_4]^{2-} & (b) \ sp^3d \\ (iii) \ [\text{Co(NH}_3)_6]^{3+} & (c) \ d^2sp^3 \\ (iv) \ \text{BrF}_5 & (d) \ dsp^2 \\ \hline \end{array}$ $\text{Correct matching is:}$

Options:

1. $\begin{array}{cccc} \text{I} & \text{II} & \text{III} & \text{IV} \\ b & d & c & a \end{array}$
2. $\begin{array}{cccc} \text{I} & \text{II} & \text{III} & \text{IV} \\ a & b & c & d \end{array}$
3. $\begin{array}{cccc} \text{I} & \text{II} & \text{III} & \text{IV} \\ b & d & a & c \end{array}$
4. $\begin{array}{cccc} \text{I} & \text{II} & \text{III} & \text{IV} \\ d & b & a & c \end{array}$

Solution:

$\text{Hint: Hybridization of P in } \text{PCl}_5 \text{ is } sp^3d$ $\begin{array}{|c|c|} \hline \text{Compound} & \text{Hybridization} \\ \hline (i) \ \text{PCl}_5 & (b) \ sp^3d \\ (ii) \ [\text{Pt(CN)}_4]^{2-} & (d) \ dsp^2 \\ (iii) \ [\text{Co(NH}_3)_6]^{3+} & (c) \ d^2sp^3 \\ (iv) \ \text{BrF}_5 & (a) \ sp^3d^2 \\ \hline \end{array}$
