Chapter 7, Problem 37P

Interpretation Introduction

Interpretation:

The formation of by product ( ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{)}}_2\text{S}$ ) should be discussed by mechanism and the reason should be explained for the occurrence in second case not in first case.

  

Concept Introduction:

The chemical reaction in which one functional group is substituted by another functional group is known as substitution reaction.

The chemical reaction in which displacement of leaving group occurs by a nucleophile is known as nucleophilic substitution reaction.

The reaction between nucleophile (electron pair donor) and electrophile (electron pair acceptor) is known as nucleophilic substitution reaction. It is classified as S_N1 and S_N2 reaction.
