Chemistry - Polymer Question with Solution | TestHub

Question Explanation:

The question asks to match four different types of polymers in Column I with their corresponding examples in Column II.

Concept :

This is based on the classification of polymers (Addition polymers, Condensation polymers, Homopolymers and Copolymers)

Solution :

(A) Addition polymers are formed by the simple addition of monomers without the elimination of any by-products. Polythene (R), Buna-S (P) and Buna-N (Q are classic examples of addition polymers.

(B) Condensation polymers are formed by the condensation reaction between monomers, resulting in the elimination of a small molecule like water. Nylon 6,6 (S) is a condensation polymer formed from adipic acid and hexamethylenediamine, with water as the by-product.

(C) Homopolymer is a polymer made from a single type of monomer unit. Polythene (R) is a homopolymer as it is made solely from ethene monomers.

(D) Copolymers are polymers made from two or more different types of monomer units. Nylon 66 (S), Buna-S (P) and Buna-N (Q) are copolymers; Nylon 6,6 (S) is a copolymer of adipic acid and hexamethylenediamine, Buna-S is a copolymer of butadiene and styrene, while Buna-N is a copolymer of butadiene and acrylonitrile.

Final Answer: (A) - P,Q,R (B) - S (C) - R (D) - P, Q,S
