Identify the set of molecules in which the central atom has only one lone pair of electrons in their valence shells
- $\mathrm{BrF}_5, \mathrm{SF}_4, \mathrm{SnCl}_2$
- $\mathrm{BrF}_5, \mathrm{XeF}_4, \mathrm{SnCl}_2$
- $\mathrm{XeF}_4, \mathrm{NH}_3, \mathrm{ClF}_3$
- $\mathrm{XeF}_6, \mathrm{ClF}_3, \mathrm{SF}_4$
Solution
$\begin{array}{|c|c|c|c|}\hline \text{Molecule} & \begin{array}{c} \text{CMVE (central} \\ \text{metal valence} \\ \text{electron)} \end{array} & \begin{array}{c} \text{Lone} \\ \text{pair} \end{array} & \begin{array}{c} \text{Bond} \\ \text{pair} \end{array} \\ \hline \mathrm{BrF}_5 & 7 & 1 & 5 \\ \hline \mathrm{SF}_4 & 6 & 1 & 4 \\ \hline \mathrm{SnCl}_2 & 4 & 1 & 2 \\ \hline \mathrm{XeF}_4 & 8 & 2 & 4 \\ \hline \mathrm{NH}_3 & 5 & 1 & 3 \\ \hline \mathrm{ClF}_3 & 7 & 2 & 3 \\ \hline\end{array}$
'So' $\mathrm{BrF}_5, \mathrm{SF}_4$ and $\mathrm{SnCl}_2$ all have 1 lone pair of electrons.
