(a) Compare the bond enthalpies (Table 8.4) of the carbon-carbon single, double, and triple bonds to deduce an average 𝜋-bond contribution to the enthalpy. What fraction of a single bond does this quantity represent?
(b) Make a similar comparison of nitrogen–nitrogen bonds. What do you observe?
(c) Write Lewis structures of N2H4, N2H2, and N2, and determine the hybridization around nitrogen in each case.
(d) Propose a reason for the large difference in your observations of parts (a) and (b).
