Q.
Which of the following statement is incorrect?
Amines
Solution:
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.
$C _{6} H _{5} NH _{2}+ NaNO _{2}+2 HCl \xrightarrow{273-278\, K } C _{6} H _{5} N _{2}^{+} Cl ^{-} + NaCl +2 H _{2} O$
Temperature must vary from $0-5^{\circ} C$.
