Consider the following:1. Cotton2. PET3. PlasticWhich of the above is...
Introduction:
In the given options, we are asked to identify the natural polymers among cotton, PET, and plastic. To determine this, we need to understand what natural polymers are and how they differ from synthetic polymers.
Natural Polymers:
Natural polymers are large molecules composed of repeating subunits found in nature. These polymers are typically derived from living organisms and can be extracted or synthesized from natural sources. Unlike synthetic polymers, natural polymers have a complex molecular structure and are biodegradable.
Analysis of the Options:
Let's analyze each option to determine if it is a natural polymer:
1. Cotton: Cotton is a natural polymer. It is composed of cellulose, a complex carbohydrate, which is a natural polymer found in the cell walls of plants. Cotton fibers are made up of long chains of cellulose molecules, making it a natural polymer.
2. PET (Polyethylene terephthalate): PET is a synthetic polymer and not a natural polymer. It is a thermoplastic polymer that is derived from petroleum. PET is commonly used in the production of bottles, containers, and polyester fibers.
3. Plastic: The term "plastic" is a broad category that includes both natural and synthetic polymers. However, in the context of the given options, it is unclear which specific type of plastic is being referred to. Some plastics, such as polypropylene and polyethylene, are derived from petroleum and are synthetic polymers. On the other hand, there are certain types of natural polymers, such as natural rubber and shellac, that can be considered as plastics. Without further information, we cannot definitively categorize "plastic" as a natural polymer.
Conclusion:
Based on the analysis, it can be concluded that cotton (option 1) is the only example of a natural polymer among the given options. PET (option 2) is a synthetic polymer, and the categorization of "plastic" (option 3) as a natural polymer is ambiguous without additional information. Therefore, the correct answer is option 'A' - 1 only.

Consider the following:1. Cotton2. PET3. PlasticWhich of the above is...
- A polymer is made up of many small units. A polymer can be either natural or synthetic. Cotton is a natural polymer, called cellulose.
- Cellulose comprises many molecules of glucose monomers. Wool, silk and leather are also examples of natural polymers. Synthetic fibres are obtained from the chemical reaction of petrochemicals.
- Polyethylene Terephthalate is a synthetic polymer, a common example of polyester. It is used to make bottles, utensils, film, wires, and other essential products. Like synthetic fibres, plastic is also a polymer. Polythene (polyethene) is an example of plastic. Plastic takes many years to decompose, hence it is not environment friendly.
