The product formed by the reaction of an aldehyde with a primary amine is:

Solution & Explanation

\textbf{Answer:} (A) Schiff base \textbf{Solution:} An aldehyde $>\mathrm{C}=\mathrm{O}$ reacts with a primary amine $\mathrm{R}-\mathrm{NH}{}_2$ by nucleophilic addition followed by loss of water, giving an imine $>\mathrm{C}=\mathrm{N}-\mathrm{R}$. Such an imine formed from a carbonyl compound and a primary amine is called a Schiff base.
