Isomers

Reactivity:

Step-by-step solution

Isomers

Isomers are the molecules with the identical molecular formula but differ in the arrangements of atoms in space.

When atoms assume different configurations, the phenomenon is termed isomerization.

SN2reaction

It is a nucleophilic substitution reaction in which an old bond is broken, and a new bond is formed. Both processes co-occur. Hence, it’s a single-step reaction.

The two reacting species are involved in the rate-determining steps.

$S_{N^2}$$S_{N^2}$reactions are fast shown with the primary bromoalkane than the secondary bromoalkane

So, the reactivity of the isomers of bromobutane is shown:
