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 :

• A

  (A) and (B) only
• B

  (D) and (E) only
• Correct answer
  C

  (B) and (D) only
• D

  (B) and (C) only

Solution

(C) Only primary amine gives carbyl amine test (D) Benzene sulphonyl chloride $\mathrm{Ph}-\mathrm{SO}_2 \mathrm{Cl}$ $\qquad$ Hinsberg reagent (E) Tertiary amine do not react with $\mathrm{Ph}-\mathrm{SO}_2 \mathrm{Cl}$ So correct options are (B) and (D) only

Hence, the correct answer is option: 'C'.
