Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 7 electrons present in nitrogen and 9 electrons in fluorine.
(a) The number of electrons present in molecule = 7 + 9 = 16
The molecular orbital configuration of molecule will be,
The formula of bonding order =
The bonding order of =
(b) The number of electrons present in molecule = 7 + 9 - 1 = 15
The molecular orbital configuration of molecule will be,
The bonding order of =
(c) The number of electrons present in molecule = 7 + 9 + 1 = 17
The molecular orbital configuration of molecule will be,
The bonding order of =
