2	Nylon	b	Artificial fibre
3	Thermosetting Plastic	c	Pipelines
4	PVC	d	Cloths

1. 1-c, 2-d, 3-b, 4-a
2. 1-b, 2-c, 3-d, 4-a
3. 1-d, 2-b, 3-a, 4-c
4. 1-d, 2-c, 3-b, 4-a

Answer 1

Correct Answer - Option 3 : 1-d, 2-b, 3-a, 4-c

Concept:

Synthetic Fibres:

• Synthetic fibre is a chain of small units joined together.
• Each small unit is a chemical substance called monomers.
• Many small units of monomers join to form polymers.
• Repeating units of polymers make up the fibre.
• Fibres that are man-made are known as synthetic fibres.
• Polymers or fibres are also found in nature, some examples of that will be cotton, silk etc.

Types of Synthetic Fibres are:

• Rayon
• Nylon
• Polyester and Acrylic

Explanation:

Rayon:

• Rayon is a synthetic fibre whose properties are similar to that of silk.
• Rayon is obtained from a natural source like wood pulp.
• It has a very shiny appearance and is hence called artificial silk.

​Nylon:

• It is also a man-made fibre.
• It is synthesized from coal, water and air.
• It is very strong, light and elastic in nature.
• Nylon is stronger than steel and is used to make ropes for mountain climbing, socks, sleeping bags, curtains, tents, car seat belts etc.

Thermosetting plastics:

• Plastic is also a polymer like synthetic fibre.
• There are two types of plastics: thermoplastics and thermosetting plastics.
• Thermosetting plastics are the ones which when moulded once cannot be softened by heating.
• It is used in making kitchenware, floor tiles, electrical switches etc.

PVC:

• PVC stands for Poly Vinyl Chloride.
• It is a plastic that gets deformed easily when heated and can be moulded again into other forms.
• It is used to make pipes, containers, various types of toys etc.
• It is thermoplastic.

The correct match is thus:

1	Rayon	d	Clothes
2	Nylon	b	Artificial fibre
3	Thermosetting Plastic	a	Coating of non-stick
4	PVC	c	Pipelines

Hence, the correct option is: 1-d, 2-b, 3-a, 4-c.
