Final answer:
The correct option for azo dye formation is 'b) Amine + Diazonium Salt → Azo Dye + Byproducts', which involves a coupling reaction between an amine and a diazonium compound to form an azo dye with the characteristic nitrogen-nitrogen double bond.
Step-by-step explanation:
The correct chemical equation for azo dye formation is "b) Amine + Diazonium Salt → Azo Dye + Byproducts". Azo dyes are created through a coupling reaction between an aromatic amine and a diazonium compound, which results in the formation of a new nitrogen-nitrogen double bond. This type of reaction is commonly used in the dyeing industry for the production of vivid and variously colored materials.
An example of a diazo coupling reaction that results in an azo dye could look something like this: Aniline (an aromatic amine) reacts with benzenediazonium chloride to produce a brightly colored azo compound and hydrochloric acid as a byproduct.
