(a)

Interpretation Introduction

Interpretation: For a given compound set of compounds, the given amines are to be prepared via two different methods of reductive amination using ammonia as a nitrogen source

Concept Introduction: Sodium cyanoborohydride is a strong reducing agent than sodium borohydride.  It reduces the carbonyl group into amine group in a rapid way.  So, it is called as reductive amination reactions.  Aldehyde or ketone group is reacted with ammonia in the presence of sodium cyanoborohydride as a reducing agent and a proton source in the reaction medium to produce primary amines.
