Chemical Reactions Diazonium Salts

The video tutorial explains the chemical reactions of diazonium salts, dividing them into two main categories: reactions where nitrogen is displaced and reactions where the diazo group is retained. It covers various replacement reactions, including those with halide, cyanide, iodide, fluoride, and hydroxyl groups, as well as reduction processes. The video also discusses coupling reactions where the diazo group acts as an electrophile, leading to the formation of compounds like P-hydroxyazobenzene and P-aminoazobenzene.
