The number of lone pairs of electrons on central atom in various given species are

Species	Number of lone pairs on central atom
$I F_{7}$	nil
$I F_{5}$	1
$Cl F_{3}$	2
$X e F_{2}$	3

Thus the correct increasing order is

0 I F_{7} < 1 I F_{5} < 2 Cl F_{3} < 3 X e F_{2}

Q. Which of the following is the correct and increasing order of lone pair of electrons on the central atom?

$I F_{7} < I F_{5} < Cl F_{3} < X e F_{2}$

$I F_{7} < X e F_{2} < Cl F_{2} < I F_{5}$

$I F_{7} < Cl F_{3} < X e F_{2} < I F_{5}$

$I F_{7} < X e F_{2} < I F_{5} < Cl F_{3}$

The number of lone pairs of electrons on central atom in various given species are

Species Number of lone pairs on central atom

$I F_{7}$ nil

$I F_{5}$ 1

$Cl F_{3}$ 2

$X e F_{2}$ 3

Thus the correct increasing order is
$0 I F_{7} < 1 I F_{5} < 2 Cl F_{3} < 3 X e F_{2}$
