Question

Write the equations showing the conversion of aniline diazoniumchloride to
a) chlorobenzene, b) Iodobenzene and c) Bromobenzene

Answer 1

a) Conversion of aniline diazonium chloride to chloro benzene
`C_(6)H_(5)N_(2)^(+)Cl^(-) overset(CH_(2)Cl_(2)//HCl) to C_(6)H_(5)Cl+N_(2)`
b) Conversion of aniline diazonium chloride to Iodo benzene
`C_(6)H_(5)N_(2)^(+)Cl^(-)+KI to C_(6)H_(5)I+N_(2)+KCl`
c) Conversion of aniline diazonium chloride to Bromo benzene
`C_(6)H_(5)N_(2)^(+)Cl^(-) overset(Cu_(2)Br_(2)//HBr) to C_(6)H_(5)Br+N_(2)`
