Those in which halogen atom is attached on unsaturated carbon atoms. 09.Haloalkanes and Haloarenes . Alkyl lithiums react with copper halides to form higher alkanes (Corey-House synthesis), Among alkyl halides, order of reactivity is I > Br > Cl > F, The reactivity of a metal toward an alkyl halide depends upon its reduction potential; more easily a metal is reduced, more reactive it is, e.g. Featured For You. However, simple aryl halides undergo nucleophilic substitution very easily by strong basic nucleophiles, like amide ion, via benzyne mechanism. IIT JEE BOOKS PDF. A. R. Reddy explains all the concepts of Haloalkanes and Haloarenes in simple and easy to understand language. Remember triple bond of benzyne is different from the triple bond of alkynes, in benzyne one of the p bonds is formed by p–p overlap while the other by sp, Remember that halogens are deactivating but o, p–directing.
