{'nylon': [0, 0, 0, 2], 'monomers': [0, 0, 0, 1], 'formaldehyde': [0, 0, 0, 2], 'hexamethylenediamine': [0, 0, 0, 1], 'synthesis': [4, 0, 0, 9], 'monomer': [0, 0, 0, 1], 'caprolactam': [0, 0, 0, 1], 'adipic acid': [0, 0, 0, 1]}
The monomers used for the synthesis of Nylon 6 are caprolactam.
Option 1: Hexamethylenediamine and adipic acid are the monomers used for the synthesis of Nylon 66, not Nylon 6.
Option 3: Urea and formaldehyde are used for the synthesis of urea-formaldehyde resin, which is a type of polymer used in the production of adhesives and coatings.
Option 4: Phenol and formaldehyde are used for the synthesis of phenol-formaldehyde resin, commonly known as Bakelite, which is used in electrical insulators and molded parts.
So, the monomers used specifically for the synthesis of Nylon 6 are caprolactam.
