Question:
Write chemical equations for the reaction of (x) ethanamine with HCl and (y) aniline with \( NaNO_2 \) and dilute HCl at \( 0^\circ C \).
Write chemical equations for the reaction of (x) ethanamine with HCl and (y) aniline with \( NaNO_2 \) and dilute HCl at \( 0^\circ C \).
Show Hint
Primary aromatic amines undergo diazotization to form diazonium salts, while aliphatic amines form ammonium salts with acids.

Solution and Explanation
(x) Reaction of ethanamine with HCl:
\[
CH_3CH_2NH_2 + HCl \rightarrow CH_3CH_2NH_3^+Cl^-.
\]
(y) Reaction of aniline with \( NaNO_2 \) and dilute HCl:
\[
C_6H_5NH_2 + NaNO_2 + 2HCl \xrightarrow{0^\circ C} C_6H_5N_2^+Cl^- + 2H_2O.
