(C) To determine the number of lone pairs on the central atom,we use the formula: $	ext{Lone pairs} = \frac{1}{2} (V - N)$,where $V$ is the number of valence electrons of the central atom and $N$ is the number of monovalent atoms bonded to it.$1$. For $ClF_3$: $V = 7, N = 3$. $	ext{Lone pairs} = \frac{1}{2} (7 - 3) = 2$.$2$. For $NF_3$: $V = 5, N = 3$. $	ext{Lone pairs} = \frac{1}{2} (5 - 3) = 1$.$3$. For $SF_4$: $V = 6, N = 4$. $	ext{Lone pairs} = \frac{1}{2} (6 - 4) = 1$.$4$. For $XeF_4$: $V = 8, N = 4$. $	ext{Lone pairs} = \frac{1}{2} (8 - 4) = 2$.CompoundLone pairs$ClF_3$$2$$NF_3$$1$$SF_4$$1$$XeF_4$$2$Therefore,the correct sequence is $2, 1, 1, 2$.

The number of lone pairs of electrons on the central atom of $ClF_3, NF_3, SF_4,$ and $XeF_4$ respectively are:
