Give the structure of ‘A’ in the following reaction.
The product formed in this chemical reaction is 3-Methylnitrobenzene.
The structure of 3-Methylnitrobenzene is:
2-Nitro-4-methylaniline reacts with NaNO2 + HCl at 273-278K and form a stable 3-diazonium salt derivate. Then it reacts with H3PO2 and water to form 3-Methylnitrobenzene as the major product. The byproducts formed in this reaction are H3PO3, HCl and N2 gas.
