SN^(2) reaction is a bimolecular reaction which takes places by the formation of T.S. Veolcity of the reaction depends on the concentration of the substrate as well as the nucleophile. The reaction is favoureed by strong Nu^(o-) and in the presence of polar aprotic sovlent, optically active halides give. Walken inversion by SN^(2) mechanism. The presence of hero group (atom) at beta-C atom,unsaturation at beta-C and(-overset(O)overset(||)(C)-) group at alpha-C atomn favor SN^(2) mechanism. Allyl halides and benzyl halides give SN^(1) andSN^(2) reactions. Allyl halides alos give SN^(2) mechanism EDG at ortho- and para-postions in benzyl halides favors SN^(1)mechanism, wheras EWG favors SN^(2) mechanism.
