Match List - I with List - II.
| List - I | List - II |
| (A) Polyvinyl chloride | (I) Phenol formaldehyde |
| (B) Urea-formaldehyde | (II) Ethyleneglycol and phthalic acid |
| (C) Glyptal | (III) Vinyl chloride |
| (D) Bakelite | (IV) Urea-formaldehyde |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Each polymer is named after, or made from, its monomers: addition polymers from one unsaturated monomer, condensation polymers from two monomers that join with loss of water.
(A) Polyvinyl chloride — This matches (III) Vinyl chloride. PVC is the addition polymer of \( \ce{CH2=CHCl} \).
(B) Urea-formaldehyde — This matches (IV) Urea-formaldehyde. The resin is the condensation polymer of urea and formaldehyde.
(C) Glyptal — This matches (II) Ethyleneglycol and phthalic acid. Glyptal is a polyester of these two monomers.
(D) Bakelite — This matches (I) Phenol formaldehyde. Bakelite is the cross-linked phenol-formaldehyde resin.
Note: This question is from the pre-rationalised NCERT book (2022-23). The topic is not there in the latest NCERT book (2026-27), and it is also out of the CUET 2026 syllabus.
NCERT (Pre-rationalised edition, 2022-23):
Some Commercially Important Polymers – “… Polyvinyl chloride (PVC) — Vinyl chloride
Urea-formaldehyde Resin — (a) Urea (b) Formaldehyde
Glyptal — (a) Ethylene glycol (b) Phthalic acid
Bakelite — (a) Phenol (b) Formaldehyde”
