The gamma-radiation-induced free-radical chain reactions in liquid CC14-C&L-c-CsHly mixtures were studied in the temperature range of 363-448Β°K. T h e main products in this system are chloroform, hexachloropropene and chlorocyclohexane. These products are formed via reactions (1)-( 5): (1) with G

β¦ Synopsis
The significance of numerical data derived from Hueckel's classical zero-order M.O. treatment for the interpretation ofreactivities towards CC13 radicals is critically discussed. Attention is called to polar and steric effects as the main causes of discrepancies.

The gas phase photolysis of CCl, in the presence of several alkanes has been used to obtain Arrhenius parameters for the abstraction of hydrogen atoms by the cc& radical: (4) Cc1, + RH -% CRCI, + R The following log k4 values were obtained: 2,3-Dimethylbutane C -C ~H I ~ Methy lcy clohexane log k4 1
## Abstract The Arrhenius parameters for the reactions equation image and equation image have been measured. Reaction (2a) was generated and studied by the photolysis of tetrachloromethane in the presence of trichlorosilane and reaction(2b) by the photolysis of 1,1,1,βtrichlorotrifluoroethane i
The photolysis of carbon tetrachloride in the presence of a number of organosilicon compounds has been investigated in the gas phase. The products obtained from the photolysis experiments were those expected from a chain reaction in which trichloromethyl radicals abstract hydrogen atoms from the org
The preceding paper describes the reanalysis by Kerr and Parsonage (following discussions with one of us, H.W.S.) of some of our published work. We are grateful to Dr. Kerr for communicating their conclusions to us. We agree in principle with their analysis, and the present communication is to repor
