MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Addition polymerization involves the repeated addition of monomer molecules possessing double or triple bonds to form a polymer, without the elimination of any small molecules. Option (322647) represents Polyacrylonitrile (PAN), which is formed by the addition polymerization of acrylonitrile ( CH _2= CH - CN ). Option (322648) represents Nylon-6, which is a condensation polymer of caprolactam. Option (322649) represents Terylene (Dacron), which is a condensation polymer of ethylene glycol and terephthalic acid. Option (322650) represents PHBV, which is a condensation polymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid. Therefore, the polymer obtained by addition polymerization is Polyacrylonitrile. Answer:
