Read the passage given below and answer the following questions:Nucleophilic substitution reactions are of two types; substitution nucleophilic bimolecular (SN2) and substitution nucleophilic unimolecular (SN1) depending on molecules taking part in determining the rate of reaction. Reactivity of alkyl halide towards SN1 and SN2 reactions depends on various factors such as steric hindrance, stability of intermediate or transition state and polarity of solvent. SN2 reaction mechanism is favoured mostly by primary alkyl halide or transition state and polarity of solvent, SN2 reaction mechanism is favoured mostly by primary alkyl halide then secondary and then tertiary. This order is reversed in case of SN1 reactions.Q. The most reactive nucleophile among the following is

Passage IIn a SN2 reaction, solvent plays a very important role. Hydroxylic solvents like water, alcohols, carboxylic acids etc., solvate nucleophile, decreases its reactivity in the reaction.Size of donor atom of nucleophile also affect nucleophilicity. A larger donor atom is more easily polarised and less solvated, hence a stronger nucleophile. Therefore, in a given group of periodic table, nucleophilicity increases down the group. However solvation effect is more predominant than polarisability.Q.Which of the following describe correctly the role of H2O a s solvent in a SN2 reaction?

View answer

Nucleophiles which have more than one type of donor atoms within the same donor group are known as ambident nucleophile e.g.CN-: Both carbon and nitrogen are donor.OCN-: Both oxygen and nitrogen are donor etc.In case of free anionic and ambident nucleophiles, the better donor atom donate its lone pair of electron and forms bond with a-carbon after substitution reaction, in a given period, donor ability decreases from left to right. In a group, donor ability increases from top to bottom.Q.When iodomethane is treated with sodium isocyanate (NaNCO), CH3NCO is the major product while AgNCO gives CH3CH2OCN as major product because
