(a)

Interpretation Introduction

Interpretation:

Organic product that is formed in the given reaction has to be classified as primary amine, secondary amine, tertiary amine or quaternary salt.

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,

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

Amine is an organic derivative.  If in ammonia one or more alkyl, cycloalkyl, or aryl groups are substituted instead of hydrogen atom then it is known as amine.  Depending on the number of substitution the amines are classified as primary, secondary or tertiary amine.  Primary amine is the one in which only one hydrogen atom in ammonia is replaced by a hydrocarbon group.  Secondary amine is the one in which only two hydrogen atoms in ammonia is replaced by a hydrocarbon group.  Tertiary amine is the one in which all three hydrogen atoms in ammonia is replaced by a hydrocarbon group.  The generalized structural formula for all the amines is,

Quaternary ammonium salt is the one that has four carbon atoms attached to the nitrogen atom.  This is formed by the reaction of tertiary amine with alkyl halide in presence of a strong base.

Answer to Problem 6.63EP

Organic product is a primary amine.

Explanation of Solution

Given reaction is,

The reactants given in the above reaction are ammonia, propyl chloride.  Sodium hydroxide is a reagent that is used for basic condition in this case.  As the reaction between ammonia and propyl chloride gives propylamine as the product, this is an alkylation reaction.  The complete reaction can be given as,

The organic product formed is propylamine.  Considering the nitrogen atom in propylamine, it is bonded to one carbon atom and two hydrogen atoms.  Hence, it is a primary amine.

Conclusion

The organic product formed in the given reaction is classified.
