JEE Main 2025 — 28 January, Evening Shift — Question 39

Identify correct statements :

(A) Primary amines do not give diazonium salts when treated with $\mathrm{NaNO}_{2}$ in acidc condition.

(B) Aliphatic and aromatic primary amines on heating wth $\mathrm{CHCl}_{3}$ and ethanolic KOH form carbylamines.

(D) Benzenesulfonyl chloride is known as Hinsberg's reagent.

(E) Tertiary amines reacts with benzenesulfonyl chloride very easily.

Choose the correct answer from the options given below :

(A) $\mathrm{R}-\mathrm{NH}_{2} \xrightarrow[\mathrm{HCl}]{\mathrm{NaNO}_{2}} \mathrm{R}-\mathrm{N}_{2}^{\oplus} \mathrm{Cl}^{\ominus}$

(B)

(D) $\mathrm{Ph}-\mathrm{SO}_{2} \mathrm{Cl} \quad \longrightarrow$ Hinsberg reagent

Benzene sulphonyl chloride

(E) Tertiary amine do not react with $\mathrm{Ph}-\mathrm{SO}_{2} \mathrm{Cl}$

So correct options are (B) and (D) only
