Match List I with List II.

Choose the correct answer from the options given below:

A-IV, B-III, C-II, D-I

The correct answer is Option (2) → A-IV, B-III, C-II, D-I.

Let us break down each item from List I and List II to understand their properties, uses, and how they match up:

A. Nylon-6,6: IV. Textile industry

Nylon-6,6 is a type of synthetic polymer, specifically a polyamide. It is made from hexamethylenediamine and adipic acid.

Primarily used in the textile industry for making strong, durable fabrics. It’s known for its excellent abrasion resistance and is often found in clothing, carpets, and industrial textiles.

Nylon's main application is in textiles, making it a key material for fabrics.

B. Bakelite: III. Switches

Bakelite is one of the first synthetic plastics, made from phenol and formaldehyde. It’s a thermosetting plastic, meaning it hardens permanently when molded.

Uses: Bakelite is known for its electrical insulating properties and heat resistance. It is commonly used in electrical applications such as switches, insulators, and casing for electronic devices.

Bakelite is widely used for making switch covers and other electrical components due to its durability and insulating properties.

C. Polyvinyl chloride: II. Wire coverings

PVC is a synthetic plastic polymer made from the polymerization of vinyl chloride. It can be made flexible or rigid depending on how it is processed.

Uses: Rigid PVC is used in construction for pipes and fittings, while flexible PVC is used for electrical cable insulation and other applications. Its excellent insulating properties make it ideal for wire coverings.

PVC is extensively used as an insulating material for electrical wires due to its non-conductive nature.

D. Melamine : I. Crockery

Melamine is a nitrogen-rich organic compound used to create a variety of products, primarily in combination with formaldehyde to produce melamine resin.

Uses: Melamine resin is used to create durable, heat-resistant surfaces, such as in dinnerware, laminate flooring, and kitchenware. It’s particularly popular for making melamine dishes and crockery.

Melamine is commonly used to produce lightweight, durable dinnerware that resembles ceramic.

The correct answer is: A-IV, B-III, C-II, D-I.
