Relationship Between Electronic Configuration and Molecular Behaviour

15 RELATIONSHIP BETWEEN ELECTRONIC CONFIGURATION AND MOLECULAR BEHAVIOUR 

Bond order The term bond order refers to the number of bonds existing between two atoms. While electrons in the bonding molecular orbitals help in the formation of covalent bonds, those in antibonding molecular orbitals oppose it. Botid order is defined as one half of the difference between the number of electrons in the bonding molecular orbitals Ni and the number of electrons in the anti-bonding molecular orbitals N.  

Stability of the molecules Bond order is a measure of the stability of the molecule. Higher the bond order greater is the stability of the molecule. Thus, 

Bond length Bond length is inversely related to bond order. The higher the bond order, the smaller the bond length. 

Paramagnetic or diamagnetic character of molecules A molecule in which all electrons are paired is diamagnetic in nature while a molecule having one or more unpaired electrons is paramagnetic in nature.
