Tertiary alkyl halide are practially inert to substitution by SN^(2) mechanism because of-

Anyl halides are practically inert toward nucleophilic substitution reactions . The reasons for this fact are

A dextrorotatory alkyl halide is allowed to react with nucleophile, leading to substitution via S_N2 mode only. The product obtained

Read the given passage and answer the questions number 1 to 5 that follow: The substitution reaction of alkyl halide mainly occurs by S_N 1 and S_N 2 mechanism. Whatever mechanism alkyl halides follow for the substitution reaction to occur, the polarity of the carbon halogen bond is responsible for these substitution reactions. The rate of S_N 1 reactions are governed by the stability of carbocation whereas for S_N 2 reactions steric factor is the deciding factor. If the starting material is a chiral compound, we may end up with an inverted product or racemic mixture depending upon the type of mechanism followed by alkyl halide. Cleavage of ethers with HI also governed by steric factor and stability of carbocation, which indicates that in organic chemistry, these two major factors help us in deciding the kind of product formed 1. Predict the stereochemistry of the product formed if an optically active alkyl halide undergoes substitution reaction by S_N 1 mechanism. 2. Name the instrument used for measuring the angle by which the plane polarised light is rotated. 3. Predict the major product formed when 2-Bromopentane reacts with alcoholic KOH. 4. Give one use of CHI_3 5. Write the structures of the products formed when anisole is treated with HI.

Which one of the following compounds most readily undergoes substitution by S_(N^(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.
