β¦ Synopsis
In polychloro-2,2-difluoropropanes, where a large inductive effect results in relatively low reactivity to chlorination, the presence of additional chlorine causes an increased reactivity of the hydrogens geminal to the chlorine and a reduced reactivity of the remote (third carbon) hydrogens. The ways in which resonance, inductive effect, and steric crowding interact in the rates of chlorination of polar molecules are discussed.

A theoretical study is reported on the effect of various long-range terms in the potential energy surface on the rate constants for the reactions of strongly polar ArH~-with H20 and NH3. A rotationally adiabatic capture theory is used. It is found that dipole-dipole, dipole-induced dipole and disper
