The reactions between alkanes and chlorine or bromine. There is no reaction in the dark. In the presence of a flame, the reactions are rather like the fluorine one-producing a mixture of carbon and the hydrogen halide.The violence of the reaction drops considerably as you go from fluorine to chlorine to bromine.he reactions of the cycloalkanes are generally just the same as the alkanes, with the exception of the very small ones-particularly cyclopropane.
