Match List I with List II

LIST I (Examples) | LIST II (Type)
A. 2-Chloro-1,3-butadiene | I. Biodegradable polymer
B. Nylon 2-nylon 6 | II. Synthetic Rubber
C. Polyacrylonitrile | III. Polyester
D. Dacron | IV. Addition Polymer

Choose the correct answer from the options given below:

Answer: A → II, B → I, C → IV, D → III

Solution

-Chloro--butadiene (chloroprene) polymerises to neoprene, a synthetic rubber. Nylon--nylon-, an alternating glycine and aminocaproic acid copolymer, is a biodegradable polymer. Polyacrylonitrile is formed by chain (addition) polymerisation of acrylonitrile. Dacron, made from ethylene glycol and terephthalic acid, is a polyester. Hence chloroprene pairs with synthetic rubber, nylon--nylon- with biodegradable polymer, polyacrylonitrile with addition polymer, and Dacron with polyester.
