On the same ground, low reactivity of vinyl chloride is explained. When hydrogen atoms or atoms of alkanes are replaced by a corresponding number of halogen atoms, the compounds are called halogen derivatives of alkanes. However, simple aryl halides undergo nucleophilic substitution very easily by strong basic nucleophiles, like amide ion, via benzyne mechanism. To avoid this oxidation chloroform is always stored in dark coloured bottles filled to the brim to exclude any air. Like alkenes, it undergoes the usual addition reactions such as addition of H. It can best be prepared by allylic chlorination of propene with chlorine at about 673K (a free radical substitution). Haloalkanes are the organic compound formed by replacing a hydrogen atom by a halogen atom. Already have an account? -hybridised carbon atom, such halogens and corresponding halides are highly reactive. However, freons destruct ozone layer in the atmosphere.
