THE MONOMER OF NYLON IS

• A. Hydroxybenzene
• B. Hexanedioic acid ✓
• C. Benzene -1,-4-dicarboxylic acid
• D. Ethane-1,2-diol

The answer to the question is: B. Hexanedioic acid

Nylon is a synthetic polymer that belongs to the family of polyamides. It was first developed in the 1930s by a research team at DuPont led by Wallace Carothers. The monomer of nylon is a compound called hexanedioic acid, also known as adipic acid. This compound has the chemical formula C6H10O4 and is used in the production of nylon through a process called polycondensation. In this process, hexanedioic acid reacts with another compound called hexamethylenediamine to form the polymer known as nylon.

Hexanedioic acid is an important component in the production of nylon because it provides the necessary chemical structure for the formation of long chains of repeating units, which gives nylon its characteristic strength and durability. The reaction between hexanedioic acid and hexamethylenediamine forms an amide bond, which is a key feature of polyamides like nylon.

In summary, the monomer of nylon is hexanedioic acid, which undergoes polycondensation with hexamethylenediamine to form the polymer known as nylon.
