Write the chemical equation for the following.
Benzene diazonium chloride is treated with ice cold solution of aniline in acidic medium.
Answer
Answer
AIEquation: $\mathrm{C_{6}H_{5}N_{2}Cl} + \mathrm{C_{6}H_{5}NH_{2}} \xrightarrow{\text{acidic}\text{ }\text{medium}\text{,}\text{ }\text{273-278}\text{ }\text{K}} \mathrm{C_{6}H_{5}N=NC_{6}H_{4}NH_{2}} + \mathrm{HCl}$
Reaction: Coupling reaction
Product: 4-aminoazobenzene (p-aminoazobenzene)
Benzene diazonium chloride couples with aniline at the para position to give the yellow dye p-aminoazobenzene.
