Question

Q43. Match List I with List II (List I: A. Bakelite formaldehyde resin, B. Melamine formaldehyde resin, C. Urea formaldehyde resin, D. Bakelite & Melamine formaldehyde resin. List II: I. Condensation polymers, II. Phenol and formaldehyde, III. Melamine and formaldehyde, IV. Unbreakable cups and laminated sheets). Choose the correct answer from the options given below:

FirstInTest · Accepted Answer

Correct answer: b. A. Bakelite formaldehyde resin is formed from phenol and formaldehyde (A-II). B. Melamine formaldehyde resin is formed from melamine and formaldehyde (B-III). C. Urea formaldehyde resin is used in various applications including adhesives and some laminates, potentially like those for unbreakable cups/laminated sheets (C-IV, as implied by the solution's mapping, though melamine is more common for cups). D. Both Bakelite and Melamine formaldehyde resins are examples of condensation polymers (D-I). Thus, the option B matches with A-II, B-III, C-IV, D-I.
