Homework Answers
Nucleophiles react with diazonium salts replacing their halogen and forming diazo compounds.
The positive charge of the diazonium ion is delocalised over tw nitrogen atoms . The nucleophile cannot bond to the inner nitrogen atom , it bonds to the outer nitrogen , to give neutral azo compounds . The reaction also called as coupling occurs fast and is reversible.
The reaction is shown in the picture attached below ,please see ..

The mechanism involves donation of a hydride from ethanol to reduce the diazonium salt as shown here. After the first reaction (Step 1), each subsequent reaction uses the product of the previous step. The amounts of all reagents used, including solvents, must be sealed according to the amount of product obtained in the previous step (after saving at least 25 mg of the product for characterization and spectral analysis in each step).
