Alkanes The reaction between alkanes and fluorine This reaction is explosive even in the cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are

contain any alkyl group‚ a primary halide has one alkyl group‚ a secondary halide has two alkyl groups‚ and a tertiary halide has three. Synthesis of alkyl halides can be performed from a variety of starting materials and specific mechanisms: from alkenes by addition‚ from alkanes by substitution‚ and from alcohols via nucleophilic substitution. The reaction of alcohols with hydrogen halides‚ like HCl‚ HBr‚ and HI‚ would result to their corresponding alkyl halides and water. The formation of alkyl
