AIIMS 2018 Chemistry Biodegradable Polymers MCQ Question

Option C is correct because neoprene is synthesized from 2-chloro-1,3-butadiene, which is a chlorinated diene that undergoes polymerization to form the rubber-like material known as neoprene. In contrast, option A is incorrect as the combination of 3-hydroxybutanoic acid and 4-hydroxypentanoic acid does not specifically describe a known biodegradable polymer. Option B is misleading since Bakelite is indeed made from phenol and formaldehyde, but the statement does not pertain to the context of polymer classification. Lastly, option D is incorrect because glyptal is actually formed from the reaction of phthalic anhydride and glycerol, not ethylene glycol.
