Choose thecorrectanswer from the options given below:
Options:
Answer:
Solution:
Glyptal is a polyester formed by the condensation of ethylene glycol and phthalic acid, and it is primarily used in the manufacture of paints and lacquers. Thus, (A) matches with (iii).
Buna N is a copolymer of 1,3-butadiene and acrylonitrile. It is resistant to the action of petrol, lubricating oil, and organic solvents, and is widely used in making oil seals, tank linings, and adhesives. Thus, (B) matches with (iv).
Perspex, also known as polymethyl methacrylate (PMMA), is a transparent thermoplastic. Due to its excellent optical clarity, it is used as a shatter-resistant alternative to glass in applications like lenses, light covers, and LCD screens. Thus, (C) matches with (ii).
Polyacrylamide is a highly water-absorbent polymer that forms a gel when hydrated. It is extensively used as a medium in gel electrophoresis (PAGE) for the separation of proteins and nucleic acids. Thus, (D) matches with (i).
The correct matching is (A)-(iii), (B)-(iv), (C)-(ii), (D)-(i).
Answer: (A)-(iii), (B)-(iv), (C)-(ii), (D)-(i)
