Interpretation Introduction

Interpretation:

Using retrosynthetic analysis, a synthesis of $\text{2-bromo-3-methylbutane}$ is to be devised.

Concept introduction:

Retrosynthetic analysis is used to determine the possible steps and reagents for producing a particular compound from a given compound.

${\text{S}}_{\text{N}}\text{2}$ reactions occur with carbon atoms having the least substituents and reaction takes place with inversion of the configuration.

Aprotic solvents, good leaving groups, and good nucleophiles promote these reactions.

${\text{S}}_{\text{N}}\text{1}$ occurs via formation of a carbocation intermediate. Hence, tertiary halides preferably react by this mechanism.
