title: Protonation thermochemistry of ethyl halides.
abstract: Gas-phase basicities of ethyl halides have been accurately determined from experimental proton-transfer reaction rates. Proton affinities (PA) were deduced after consideration of the entropy change associated with the protonation process and from G2 ab initio calculations. The present PA(C2H5X) assessment (653, 679, 685, and 709 kJ mol(-1) for X=F, Cl, Br and I, respectively) indicates that the currently tabulated values should be revised downward by 10 to 30 kJ mol(-1).
