Question:

$\text{Match column I with column II:}$ $\begin{array}{|c|c|} \hline \text{Column-I (Compounds)} & \text{Column-II (number of lone pairs of a central atom)} \\ \hline \text{A. } \text{IF}_7 & \text{P. } 0 \\ \text{B. } \text{ICl}_4^- & \text{Q. } 1 \\ \text{C. } \text{XeF}_2 & \text{R. } 2 \\ \text{D. } \text{XeF}_6 & \text{S. } 3 \\ \hline \end{array}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $\text{A - P, B - Q, C - R, D - S}$
2. $\text{A - P, B - R, C - S, D - Q}$
3. $\text{A - R, B - S, C - P, D - Q}$
4. $\text{A - S, B - R, C - Q, D - P}$

Solution:

$\text{A. } \text{IF}_7 \rightarrow \text{P. } 0 \text{ lone pairs}$ $\text{B. } \text{ICl}_4^- \rightarrow \text{R. } 2 \text{ lone pairs}$ $\text{C. } \text{XeF}_2 \rightarrow \text{S. } 3 \text{ lone pairs}$ $\text{D. } \text{XeF}_6 \rightarrow \text{Q. } 1 \text{ lone pair}$
