Interpretation Introduction

Interpretation:

The bond orders for ${\text{N}}_2{}^{2+}$, ${\text{N}}_2{}^{-}$ and ${\text{N}}_2{}^{2-}$ are to be determined. Also the species are to be ranked in the order of decreasing bond energy and decreasing bond length.

Concept introduction:

The molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

Bond order is the number of bonds that an atom can form with other atoms. Higher the bond order, more will be the stability of the molecule and vice-versa.

Bond energy is the amount of heat that is needed to break the bonds between various atoms. It depends on bond order. Higher the bond order, more will be its bond energy and vice-versa. Bond length is the average distance between the centres of the atomic nuclei of the combining atoms. Its value is inversely proportional to bond order.
