Match the monomers in List-I with the corresponding polymers in List-II and choose the correct code. List I I. Hexamethylenediamine II. Phenol III. Phthalic acid IV. Terephthalic acid List II A. Bakelite B. Dacron C. Glyptal D. Melamine E. Nylon

1. I-E, II-A, III-B, IV-C
2. I-E, II-A, III-C, IV-B
3. I-D, II-C, III-A, IV-B
4. I-D, II-C, III-A, IV-B

Correct answer: I-E, II-A, III-C, IV-B

Solution

Hexamethylenediamine is a key monomer in the production of Nylon, while Phenol is used to create Bakelite. Phthalic acid is a monomer for Glyptal, and Terephthalic acid is essential for the synthesis of Dacron, making the correct matches I-E, II-A, III-C, and IV-B.
