Vedclass · Answer

(C) The reaction of aniline with nitrous acid $(HNO_2)$ in the presence of $HCl$ at $273-278 \, K$ $(0-5 \, ^\circ C)$ is known as the diazotization reaction.In this reaction,aniline is converted into benzene diazonium chloride,which is a diazo compound.The chemical equation is:$C_6H_5NH_2 + HNO_2 + HCl \xrightarrow{273-278 \, K} [C_6H_5N_2]^+Cl^- + 2H_2O$Thus,the correct option is $C$.

What is formed when aniline reacts with $HNO_2$ and $HCl$ at $273 \, K$?
