A scientist studies the bond energies of different compounds containing nitrogen (N). The scientist observes that the N–N bonds in one group of compounds have a bond energy of 209 kJ/mol, while the N–N bonds in another group of compounds have a bond energy of 418 kJ/mol. In one or two sentences, postulate a reason for this difference

The higher bond energy of 418 kJ/mol in the second group of compounds indicates that the N-N bonds are stronger and more stable compared to the N-N bonds in the first group, which have a bond energy of 209 kJ/mol. This could be due to differences in the molecular structure or electronic configuration of the compounds in each group.
