Question

calculate the bond order in o2 ?

Answer 1

The Lewis structures have an unpaired electron and an average bond order of 1.5. O2 has two unpaired electrons in its π* orbitals, and a bond order of 2.

Answer 2

As there are 10 electrons in bonding orbitals and 6 electrons in antibonding orbitals.

So,

Bond order=no.of electron in bonding orbitals-no. of electron in anti bonding orbitals /2

B.O.=10-6/2

=2

So it is para magnetic.
