Match List-I with List-II

Choose the correct answer from the options given below

We need to match the polymers in List-I with their uses in List-II.

Since Nylon 6,6 is a polyamide known for its high tensile strength and rigidity, commonly used to make bristles of brushes, textiles, and ropes, it corresponds to (III) Bristles of brushes, giving A - Nylon 6,6 → (III) Bristles of brushes.

Similarly, Low density polythene (LDPE) has a branched structure, making it soft and flexible, and is used for making squeeze bottles, toys, and packaging materials, so B - Low density polythene → (IV) Toys.

High density polythene (HDPE) has a linear structure, making it harder and more rigid than LDPE, and is used for making buckets, pipes, and bottles, which indicates that C - High density polythene → (I) Buckets.

Finally, Teflon (polytetrafluoroethylene, PTFE) is chemically inert and has a very low coefficient of friction, and is used as a coating in non-stick utensils, hence D - Teflon → (II) Non-stick utensils.

Therefore, the final matching is A - III, B - IV, C - I, D - II, and the correct option is Option B.
