Question

Write the MO configuration of the following species- O2 , O2+ , O2- , O22- Arrange them in order of their decreasing stabilities?

Answer 1

The bond length in the oxygen species ,O2+,O2,O2-,022- can be explained by positions of the electrons in molecular orbital theory
The electron configuration of the oxygen molecule must accommodate 16 electrons.The way bond order is determined is through equation:bond order=1/2(#e-in bonding MO's-#e-In antibonding MO's)
