The dissociation energy of N 2. Jan AlmlÖf. Department of Chemistry and Supercomputer Institute, University of Minnesota, Minneapolis, Minnesota 55455.
According to Molecular orbital theory: N2 have 6 more electrons in a bonding atomic orbital so it's bond order is 3, whereas N2+ has only 5 in bonding so it's bond order is 2.5. Bond dissociation energy is directly proportional to Bond order of a molecule so N2 has more bond dissociation energy.Mcculloch 4318 parts

- So if you consider that dinitrogen has a triple bond and dioxygen a double bond, you see that breaking dinitrogen into atoms requires a much higher bond dissociation energy. Also, you see that the bond length in dinitrogen is the shortest, so here your teacher's rule of thumb (shorter bond, stronger bond) works nicely. F is smaller than N and O ...

- If the bond energy of a single P−P bond is 200 kJ mol¯ 1, what is the energy of the PP triple bond in P 2? Solution: Say you break all 6 P−P bonds in P 4, that is 6 x 200 = +1200. 1200 − 217 = 983 which is released when two P≡P bonds form. So 983 / 2 = bond energy of a P≡P bond. To three sig figs, the answer is 492 kJ/mol.

- The bond-dissociation energy of N2 is very high (Table 8.4). As shown in Practice Exercise 18.2, only photons of very short wavelength possess sufficient energy to cause dissociation of this molecule. Furthermore, N2 does not readily absorb photons, even when they do possess sufficient energy.

We can determine the energy necessary to break the O-O bond in ozone with an experiment. Remember that the energy in light is proportional to its frequency and inversely proportional to the wavelength We can obtain experimental data on bond energies of other molecules in the same way.5.3-1 Calculating Enthalpy Change from Bond Energies Use the table below to answer the following questions. Table 1 Average Bond Energies (kJ/mol) Bond Energy Bond Energy H−H 432 F-F 154 H−F 565 O−H 467 C−H 413 Cl−Cl 239 C−O 358 C=C 614 C≡O 1072 C=O 745 C−C 347 C=O (for CO2(g)) 799 N2 has bond order ′3′ and N2+ , it is 2.5. Great bond order has higher bond dissosiation energy. So, bond dissociation is greater for O2+ .
