Question

Match List I with List II

List I Polymer	List II Application
(A). Glyptal	(i). Electrophoresis
(B). Buna N	(ii). LCD screen
(C). Perspex	(iii). Paints
(D). Polyacrylamide	(iv). Adhesive

Choose the correct answer from the options given below:

• A. (A)-(i), (B)-(ii), (C)-(iii), (D)-(iv)
• B. (A)-(iii), (B)-(ii), (C)-(iv), (D)-(i)
• C. (A)-(iv), (B)-(iii), (C)-(ii), (D)-(i)
• D. (A)-(iii), (B)-(iv), (C)-(ii), (D)-(i)

Hint:

Glyptal is used in paints, Buna-N in adhesives, Perspex in LCD screens and polyacrylamide in electrophoresis.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Each polymer is used for a particular purpose that follows from its properties.

Step 2: Match the first two
Glyptal (a polyester of ethylene glycol and phthalic acid) is used for paints and lacquers, so (A) matches (iii). Buna-N is oil resistant and is used in adhesives and seals, so (B) matches (iv).

Step 3: Match the other two
Perspex (poly methyl methacrylate) is transparent and used for LCD screens, so (C) matches (ii). Polyacrylamide gel is the medium for electrophoresis, so (D) matches (i).

Final Answer:
The matching is A-iii, B-iv, C-ii, D-i. \[ \boxed{\text{(D) }\text{(A)-(iii), (B)-(iv), (C)-(ii), (D)-(i)}} \]
