HOW DOES HIGH INTER ELECTRONIC REPULSION OF NON-BONDING ELECTRONS LEAD TO SMALL BOND LENGTH IN CASE OF N-N BOND?
Asked by sureshkumar kumar | 12 Feb, 2014, 10:19: AM
Expert Answer
Nitrogen possesses unshared pair or lone pair of electrons. Smaller size of Nitrogen; N leads to smaller N-N bond length. As a result, the lone pair of electrons on the both the N atoms repel each other leading to instability or weakening of N-N bond.
In other words, the N-N bond is weaker due to the interelectronic repulsion between the non-bonding electrons, owing to the small bond length in N2.
