why N-N IS STRONGER THAN P-P |
|
Answer» N-N sigma bond is weaker than P-P sigma bond due to the small bond length between the nitrogen atoms. The non-bonding electrons(lone pair of electrons) of both the atoms repel each other making it weaker than P-P sigma bond. This is why the catenation tendency is not present in Nitrogen. But nitrogen also has a tendency to form strong pπ-pπ bonds with itself which is not present in other Group 15 elements as the overlapping between the large atoms is diffuse. So the N-N π-bond is stronger than P-P π-bond. thank u |
