Q. 40

What is the effect of the following processes on the bond order in N2 and O2?

(i) N2 N2+ + e-

(ii) O2 O2+ + e-

Answer :


(i) N2 is having 14 electrons when it donates one electron, these electrons are removed from the Bonding molecular orbital.


Thus,




The bond order reduces.


(ii) O2 has 16 electrons, 8 electrons in the molecular orbitals and 4 in the antibonding molecular orbitals.


It donates one electron from the anti-molecular bonding orbital.


Thus,




The bond order increases.
