Reaction of hydrogen atoms with halogeno-methanes. Part 2.—Bromotrichloromethane and fluorotrichloromethane

Abstract

The reaction of hydrogen atoms with bromotrichloromethane and with fluorotrichloromethane has been investigated. The main course of both reactions is shown to be the same as that established in part 1 for the reaction of hydrogen atoms with carbon tetrachloride. Both reactions involve initial halogen abstraction followed by combination of the resultant trihalogenomethyl radical with a hydrogen atom to form a vibrationally excited trihalogenomethane molecule. From the experimental results it has been possible to compare the relative rates of abstraction of the different halogens and to study the fate of the different vibrationally excited trihalogenomethanes.
