	(Polymer)		(Used in)
A.	Bakelite	i	Radio and television cabinets
B.	Glyptal	ii	Electrical switches
C.	PVC	iii	Paints and Lacqures
D.	Polystyrene	iv	Water pipes

Choose the correct answer from the options given below:

• (A) –(II) (B) – (III), (C) – (IV), (D) – (I)
• (A) –(I) (B) – (II), (C) – (III), (D) – (IV)
• (A) –(IV) (B) – (III), (C) – (II), (D) – (I)
• (A) –(II) (B) – (III), (C) – (I), (D) – (IV)

Answer 1

The Correct Option is A

To solve this question, we need to match each polymer with its typical use. Let's go through each option:

1. Bakelite: This is a thermosetting polymer known for its electrical insulating properties and heat resistance. It is commonly used in making electrical switches, radio and television cabinets, and other electrical items. Therefore, Bakelite corresponds to items such as electrical switches (match with ii).
2. Glyptal: This polymer is used primarily in paints and varnishes due to its excellent adhesion and resistance to weathering and chemicals. Hence, Glyptal aligns with paints and lacquers (match with iii).
3. PVC (Polyvinyl Chloride): Known for its durability and resistance to environmental degradation, PVC is widely used for water pipes and plumbing applications. Hence, PVC should be matched with water pipes (match with iv).
4. Polystyrene: This polymer is lightweight and has good insulation properties, making it useful for manufacturing items such as packaging, insulation, and also radio and television cabinets (match with i).

Based on the above reasoning, the correct matchings are:

• A (Bakelite) – ii (Electrical switches)
• B (Glyptal) – iii (Paints and Lacquers)
• C (PVC) – iv (Water pipes)
• D (Polystyrene) – i (Radio and television cabinets)

Thus, the correct option is: (A) –(II) (B) – (III), (C) – (IV), (D) – (I).
