Which of the following statement is incorrect? (A) Benzenediazonium chloride is prepared by the reaction of aniline with nitrous acid at 273-278 K (B)  (C) The conversion of primary aromatic amines into diazonium salt is known as diazotisation (D) Diazonium salt is not generally stored, used immediately after its preparation

Tardigrade Admin · Accepted Answer

Benzene diazonium chloride is prepared by the reaction of aniline with nitrous acid at

273 - 278 K

which is known as diazotisation.
Due to its instability, the diazonium salt is not generally stored and is used immediately after its preparation.

C_{6} H_{5} N H_{2} + N a N O_{2} + 2 H Cl 273 - 278 K C_{6} H_{5} N_{2}^{+} C l^{-} + N a Cl + 2 H_{2} O

Temperature must vary from

0 - 5^{\circ} C
