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

Introduction of Diazonium Salt Preparation and Properties 1

→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.

Introduction of Diazonium Salt Preparation and Properties

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.

Introduction of Diazonium Salt Preparation and Properties

→Aromatic aryl dizaonium salt C6H5N2Cl are stable as their diazonium salt ion shows resonance and forms stable compound.
