JEE MAIN - Chemistry (2025 - 28th January Evening Shift - No. 15)
Identify correct statements :
(A) Primary amines do not give diazonium salts when treated with $\mathrm{NaNO}_2$ in acidic condition.
(B) Aliphatic and aromatic primary amines on heating with $\mathrm{CHCl}_3$ and ethanolic KOH form carbylamines.
(C) Secondary and tertiary amines also give carbylamine test.
(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 :
Explanation
(A) $\mathrm{R}-\mathrm{NH}_2 \xrightarrow[\mathrm{HCl}]{\mathrm{NaNO}_2} \mathrm{R}-\mathrm{N}_2^{\oplus} \mathrm{Cl}^{\ominus}$
(B) _28th_January_Evening_Shift_en_15_1.png)
(C) Only primary amine gives carbyl amine test
(D) _28th_January_Evening_Shift_en_15_2.png)
(E) Tertiary amine do not react with $\mathrm{Ph}-\mathrm{SO}_2 \mathrm{Cl}$
So correct options are (B) and (D) only
