Question

Write the important conditions required for the linear combination of atomic

orbitals to form molecular orbitals.

(ii) Use molecular orbital theory to explain why the Be2 molecule does not exist.



(iii) Arrange in increasing order of stability: O2, O2

+, O2

-, O2

2- . ​

Answer 1

Answer:

For the formation of proper molecular orbital, proper energy and orientation are required. For proper energy, the two atomic orbitals should have the same energy of orbitals and for the proper orientation, the atomic orbitals should have proper overlap and the same molecular axis of symmetry.
