| Sumario: | Nucleophilicities N of prototype saturated and unsaturated hydrocarbons methane, ethane, cyclopropane, ethyne and ethene when acting as Lewis bases were determined from the dissociation energies D of the hydrogen-bond complexes B…HX calculated ab initio, where B is the hydrocarbon and HX is variously HF, HCl, HBr, HI, HCN, HCCH and HCP. The values of N obtained were 0.712(31), 0.736(32), 0.283(44), 2.561(73), 2.604(51) for methane, ethane, cyclopropane, ethyne and ethene, respectively. The inductive effect of the methyl group when ethyne is methylated was also investigated. |
