Question

What product would you expect from ${\mathbf{S}}_{\mathbf{N}}\mathbf{2}$ reaction of 1-bromobutane with each of the following?

(a) NaI (b) KOH (c) $\mathbf{H}\mathbf{—}\mathbf{C}\equiv \mathbf{C}\mathbf{—}\mathbf{Li}$ (d) ${\mathbf{NH}}_{\mathbf{3}}$

Step-by-Step Solution

Answer

(a)

(b)

(c)

(d)

Nucleophilic bimolecular substitution S N 2 reaction

The reaction is a nucleophilic substitution reaction where bond is broken and another is formed simultaneously. Two reacting species are involved in the rate determining step of the reaction. The term stands for substitution nucleophilic bimolecular.

                                                                         ${\mathrm{S}}_{\mathrm{N}}2$Reaction

Determine the product of the S N 2 reaction of 1-bromobutane with each of the following

(a) NaI with 1-bromobutane

(b) KOH with 1-bromobutane

(c) $\mathrm{H}—\mathrm{C}\equiv \mathrm{C}—\mathrm{Li}$ with 1-bromobutane

(d) ${\mathrm{NH}}_3$ with 1-bromobutane
