Identify the product ' \(A\) ' in the following reaction. \({\text{Aniline }}\xrightarrow[{{\text{Pyridine}}}]{{{{\left( {{\text{C}}{{\text{H}}_{\text{3}}}{\text{CO}}} \right)}_{\text{2}}}{\text{O}}}}{\text{A}}\)
1 Sulphanilic acid
2 Benzenediazonium chloride
3 Acetanilide
4 \(p\)-nitroacetanilide
Explanation:
The product (A) is acetanilide. Amino group of aniline is acetylated with acetic anhydride/pyridine. It is an electrophilic substitution reaction. In this reaction pyridine being a base is used to remove the side product, i.e., \(\mathrm{HCl}\) from reaction mixture.
