) 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. Lesson 2, Page 9

The difference in bond energies between the two groups of compounds may be due to the different molecular structures or environments surrounding the N–N bonds, which can affect the strength of the bonds.
