Conclusions 1.Ozone forms 1:1 complexes with benzene, fluorobenzene, chlorobenzene, bromobenzene, toluene, ethylbenzene, and benzyl chloride. Stability constants have been determined for these complexes at -10°C.2.A study of the relation between the logarithm of the equilibrium constant and the Hammetts-m values for the various substituents log K0=-0.54,?=-1.74 has shown the inductive effect from the substituent X to be the principal factor in fixing the equilibrium constant in reactions of the ArX+O3?ArX·O3 type.3.The values of the heats of complexing of ozone with mono substituted benzenes (?H0) range from -1.4 to -2.6 kcal/mole, while the corresponding entropies of formation (?S0) range from -9.9 to -11.8 cal/ (mole·deg), values close to those for aromatic hydrocarbon complexes with acceptors such as iodine, iodine monochloride, and sym-trinitrobenzene. |
