The gas phase photolysis of CCl 4 in the presence of several alkanes has been used to obtain Arrhenius parameters for the abstraction of hydrogen atoms by the CCl 3 radical:The following log k 4 values were obtained:TextRH log k 4c ‐C 5 H 10 ,\documentclass{article}\pagestyle{empty}\begin{document}$$12.00 \pm 0.21 - \frac{{10,700 \pm 400}}{{2.3RT}}$$\end{document}n‐C 6 H 14\documentclass{article}\pagestyle{empty}\begin{document}$$11.81 \pm 0.18 - \frac{{10,800 \pm 300}}{{2.3RT}}$$\end{document}2,3‐Dimethylbutane\documentclass{article}\pagestyle{empty}\begin{document}$$10.88 \pm 0.11 - \frac{{8,200 \pm 200}}{{2.3RT}}$$\end{document}c ‐C 7 H 14\documentclass{article}\pagestyle{empty}\begin{document}$$12.07 \pm 0.43 - \frac{{9,900 \pm 800}}{{2.3RT}}$$\end{document}Methylcyclohexane\documentclass{article}\pagestyle{empty}\begin{document}$$11.75 \pm 0.26 - \frac{{9,900 \pm 500}}{{2.3RT}}$$\end{document}c ‐C 8 H 16\documentclass{article}\pagestyle{empty}\begin{document}$$12.11 \pm 0.29 - \frac{{9,600 \pm 500}}{{2.3RT}}$$\end{document}The results are compared to those for CH 3 and CF 3 radicals.
