प्रश्न
Account for the following :
N − N single bond is weaker than P − P single bond.

उत्तर
N-N single bond is weaker than P-P bond due to smaller size of N as compared to P. Smaller size of 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 unstability or weakening of N-N bond.
