Current Question (ID: 8056)

Question:

Match the compounds of $\text{Xe}$ in column $\text{I}$ with the molecular structure in column $\text{II}.$ $\text{Column-I}\hspace{20mm}\text{Column-II}$ $(\text{a})\text{ }\text{XeF}_2\hspace{20mm}(\text{i})\text{ Square planar}$ $(\text{b})\text{ }\text{XeF}_4\hspace{20mm}(\text{ii})\text{ Linear}$ $(\text{c})\text{ }\text{XeO}_3\hspace{20mm}(\text{iii})\text{ Square pyramidal}$ $(\text{d})\text{ }\text{XeOF}_4\hspace{18mm}(\text{iv})\text{ Pyramidal}$

Options:

1. (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
2. (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
3. (a)-(ii), (b)-(iii), (c)-(i), (d)-(iv)
4. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii) (Correct)

Solution:

$\text{HINT: Molecular structure will depend on the lone pairs.}$ $\text{Explanation:}$ $\text{Molecule}\hspace{10mm}\text{Hybridisation}\hspace{10mm}\text{Molecular structure}$ $\text{XeF}_2\hspace{18mm}\text{sp}^3\text{d}\hspace{20mm}\text{Linear}$ $\text{XeF}_4\hspace{18mm}\text{sp}^3\text{d}^2\hspace{14mm}\text{Square planar}$ $\text{XeO}_3\hspace{18mm}\text{sp}^3\hspace{20mm}\text{Pyramidal}$ $\text{XeOF}_4\hspace{16mm}\text{sp}^3\text{d}^2\hspace{12mm}\text{Square pyramidal}$
