Introduction of Diazonium Salt Preparation and Properties
→ The diazonium compounds have the general formula
ArN2+ X– where Ar stands for an aryl group and X may be
→ion is called diazonium group. They are named by suffix diazonium to the name of the parent hydrocarbon from which they are formed followed by the name of anion.
Example :
C6H5N2Cl Benzene diazonium chloride C6H5N2HSO4, Benzene Diazonium hydrogen su1phate Aliphatic alkyl diazonium salt R—N2Cl are unstable because diazonium salt ion formed from these does not show resonance structures.
→Aromatic aryl dizaonium salt C6H5N2Cl are stable as their diazonium salt ion shows resonance and forms stable compound.
