Match the columns Column I Column II (a) Biodegradable (p) polyacrylonitrie (b) Synthetic (q) PHBV (c) Natural (r) dacron (d) Polyester (s) Rubber

Question

How is terylene prepared?

Answer 1

Let's match the given items from Column I with the correct items from Column II based on their properties:

Biodegradable: This refers to materials that can be broken down by microorganisms into natural substances like water, carbon dioxide, and compost. From the given options, PHBV (polyhydroxybutyrate-co-hydroxyvalerate) is biodegradable. Thus, \( \textbf{(a) Biodegradable} \rightarrow \textbf{(q) PHBV} \).
Synthetic: These are man-made polymers. Polyacrylonitrile is a synthetic polymer, typically used in the production of acrylic fibers and known for its strength and thermal stability. Therefore, \( \textbf{(b) Synthetic} \rightarrow \textbf{(p) polyacrylonitrile} \).
Natural: Natural materials are those that occur naturally, like rubber, silk, wool, etc. In this context, Rubber is a naturally occurring polymer obtained from the latex of rubber trees. Hence, \( \textbf{(c) Natural} \rightarrow \textbf{(s) Rubber} \).
Polyester: This is a category of polymers that primarily contains the ester functional group in their main chain. Dacron is a type of polyester. Thus, \( \textbf{(d) Polyester} \rightarrow \textbf{(r) dacron} \).

Considering the above reasoning, the correct matching order from the options is: a-q; b-p; c-s; d-r.

Natural: Natural materials are those that occur naturally, like rubber, silk, wool, etc. In this context, Rubber is a naturally occurring polymer obtained from the latex of rubber trees. Hence, \( \textbf{(c) Natural} \rightarrow \textbf{(s) Rubber} \).
Polyester: This is a category of polymers that primarily contains the ester functional group in their main chain. Dacron is a type of polyester. Thus, \( \textbf{(d) Polyester} \rightarrow \textbf{(r) dacron} \).

Considering the above reasoning, the correct matching order from the options is: a-q; b-p; c-s; d-r.

The Correct Option is A
