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, hypothesize a reason for this difference.

The difference in bond energy can be hypothesized based on the bond length and bond order. N–N bonds with higher bond order and shorter bond length have stronger bond energies, which could explain the observed difference.
