Identify correct statements : (A) Primary amines do not give diazonium salts when treated with NaNO2\mathrm{NaNO}_2 in acidic condition. (B) Aliphatic and aromatic primary amines on heating with CHCl3\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 :Identify correct statements : (A) Primary amines do not give diazonium salts when treated with NaNO_2 in acidic

Options

  1. A(A) and (B) only
  2. B(D) and (E) only
  3. C(B) and (D) only
  4. D(B) and (C) only

Correct answer

C. (B) and (D) only

Step-by-step solution

Identify correct statements : (A) Primary amines do not give diazonium salts when treated with NaNO_2 in acidic
(C) Only primary amine gives carbyl amine test (D) Benzene sulphonyl chloride Ph−SO2Cl\mathrm{Ph}-\mathrm{SO}_2 \mathrm{Cl} \qquad Hinsberg reagent (E) Tertiary amine do not react with Ph−SO2Cl\mathrm{Ph}-\mathrm{SO}_2 \mathrm{Cl} So correct options are (B) and (D) only
