(a)

Interpretation Introduction

Interpretation:

Product formed when bromomethane reacts with the given nucleophile has to be identified.

Concept Introduction:

• The ${\text{S}}_{\text{N}}\text{2}$ reaction is a type of reaction mechanism in which one bond is broken and one bond is formed i.e., in one step. ${\text{S}}_{\text{N}}\text{2}$ is a kind of nucleophilic substitution reaction mechanism.
• The nucleophile attacks the back side of the carbon that is attached to the halogen. Therefore it takes an inversion of configuration.
• The configuration of the product is inverted relative to the configuration of the reactant.

(b)

Interpretation Introduction

Interpretation:

Product formed when bromomethane reacts with the given nucleophile has to be identified.

Concept Introduction:

• The ${\text{S}}_{\text{N}}\text{2}$ reaction is a type of reaction mechanism in which one bond is broken and one bond is formed i.e., in one step. ${\text{S}}_{\text{N}}\text{2}$ is a kind of nucleophilic substitution reaction mechanism.
• Steric effect is the effect due to the groups occupies a certain volume of space.
• Steric hindrance is caused by the bulky groups at the site of a reaction that makes it difficult for the reactants to approach each other.

(c)

Interpretation Introduction

Interpretation:

Product formed when bromomethane reacts with the given nucleophile has to be identified.

Concept Introduction:

• The ${\text{S}}_{\text{N}}\text{2}$ reaction is a type of reaction mechanism in which one bond is broken and one bond is formed i.e., in one step. ${\text{S}}_{\text{N}}\text{2}$ is a kind of nucleophilic substitution reaction mechanism.
• Aprotic solvent are polar solvent molecules which do not have hydrogen bonded to oxygen to nitrogen.
• Protic solvent are polar solvent molecules which do have hydrogen bonded to oxygen to nitrogen.
• The stronger base is always a better nucleophile in an aprotic solvent.
