Match List - I with List - II.

Choose the correct answer from the options given below :

(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

The correct answer is option 2. (A)-(II), (B)-(IV), (C)-(I), (D)-(III).

(A) Nylon 2-Nylon 6: (II) Glycine and Amino caproic acid:

Nylon 2-nylon 6 can be formed by polyamide copolymerization. This reaction takes place between two monomers namely Glycine and amino caproic acid. The formula for glycine is \(NH_2CH_2COOH\) and the formula for amino caproic acid is \(NH_2(CH_2)_5COOH\). This a type of condensation reaction in which when n moles of glycine, \(NH_2CH_2COOH\) and \(n\) moles of amino caproic acid, \(NH_2(CH_2)_5COOH\) will react and further removal of water molecules takes place giving rise to the polymer, Nylon 2-Nylon 6. The reaction is given below:

(B) Neoprene : (IV) 2-chlorobuta-1,3-diene:

Chloroprene is the monomer of neoprene. Chloroprene repeats itself to form repeating units, which inturn forms neoprene, a polymer.

(C) Glyptal : (I) Ethylene glycol and Benzene-1,2-dicarboxylic acid

The structure of Glyptal is made up of two monomers Ethylene glycol and Phthalic acid as shown in the Reaction. It is a type of a copolymer as it is made by polymerization of two monomers. It is used in binding materials and cements.

(D) Nylon 6, 6 :  Adipic acid and Hexamethylene diamne:

Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined in water. In the original implementation, the resulting ammonium/carboxylate salt was isolated and then heated either in batches or continuously to induce polycondensation
