Explain the factors affecting SN_(1) and SN_(2) mechanism.

SN2 Mechanism

The rate of SN^2 reaction depends on the effectiveness of the nucleophile in ejecting the leaving group. Nucleophilicity is the affinity for C atom, while basicity is the affinity for proton. In both cases, a new bond is formed. If a new bond is formed between the anion and proton, the specied acts as a base. If a new bond is formed between the anion and C atom, the species acts as nucleophile. Which of the following compounds gives SN^1, SN^2 , and SN^2 mechanisms ?

Ph--CH_(2)--O--Et (benzyl ethyl ether) iv. (1-Ethoxy-2-methyl butane) v. (2-Propoxy-2-methyl butane) vi. PhCH_(2)OPh (Benzyl phenyl ether) vii. (Tetrahydrofuran, THF) b. Given the products of the above ethers with excess of HI. c. Why does SN^(-2) cleavage occur at a faster rate with HI than with HCI ?

Explain SN^2 mechanism ?

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) and SN^(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. Which of the following will give SN^(2) mechanism?
