Vedclass · Answer

(D) To determine the number of lone pairs on the central atom,we use the formula: $	ext{Lone pairs} = \frac{V - N}{2}$,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 $IF_7$: Central atom $I$ has $7$ valence electrons. It forms $7$ bonds with $F$ atoms. $	ext{Lone pairs} = \frac{7 - 7}{2} = 0$.$2$. For $IF_5$: Central atom $I$ has $7$ valence electrons. It forms $5$ bonds with $F$ atoms. $	ext{Lone pairs} = \frac{7 - 5}{2} = 1$.$3$. For $ClF_3$: Central atom $Cl$ has $7$ valence electrons. It forms $3$ bonds with $F$ atoms. $	ext{Lone pairs} = \frac{7 - 3}{2} = 2$.$4$. For $XeF_2$: Central atom $Xe$ has $8$ valence electrons. It forms $2$ bonds with $F$ atoms. $	ext{Lone pairs} = \frac{8 - 2}{2} = 3$.The number of lone pairs is: $IF_7 (0) Thus,the correct order is $IF_7 < IF_5 < ClF_3 < XeF_2$.

Which of the following is the correct order of increasing number of lone pair of electrons on the central atom?
