Chapter 6, Problem 6.67EP

Interpretation Introduction

Interpretation:

Three different set of alkyl chloride‑secondary amine has to be given from which tertiary amine ethylmethylpropylamine can be prepared.

Concept Introduction:

Alkylation reaction is a reaction in which the transfer of alkyl group from one molecule to another molecule takes place.  While considering amines, the alkylating agent that is used is alkyl halides.  Alkylation is done under basic conditions.  The general equations for amines alkylation process is,

  $\begin{array}{l}\text{Ammonia}\text{+}\text{Alkyl}\text{halide}\stackrel{\text{Base}}{\to }\text{1°}\text{amine}\\ \text{1°}\text{amine}\text{+}\text{Alkyl}\text{halide}\stackrel{\text{Base}}{\to }\text{2°}\text{amine}\\ \text{2°}\text{amine}\text{+}\text{Alkyl}\text{halide}\stackrel{\text{Base}}{\to }\text{3°}\text{amine}\\ \text{3°}\text{amine}\text{+}\text{Alkyl}\text{halide}\stackrel{\text{Base}}{\to }\text{quaternary ammonium salt}\end{array}$
