1. According to molecular orbital theory, two atomic orbitals of almost similar in energy, shape combine to form two sets of molecular orbitals, low energy bonding orbital and high energy anti-bonding orbital. The stability of molecules can be explained using this theory

Consider Na2, the electronic configuration of sodium is 1s2 ...

Solution Summary

This solution uses the molecular orbital theory to explain why certain molecules are stable or unstable.
