Question

Which polymers occur naturally?

• A. Starch and nylon
• B. Starch and cellulose
• C. Proteins and nylon
• D. Proteins and PVC

Answer 1

The correct option is B

Starch and cellulose

Explanation for correct answer:-

Option (B) Starch and cellulose

• Polymers generally occur in three types, Natural, synthetic, and semi-synthetic in nature.
• Natural polymers are polymers that occur naturally in nature and can be found in animals, plants, and even in human beings in the form of proteins, RNA, DNA, glycose, etc,
• Thus we can say that both Starch and cellulose are both naturally occurring polymers.
• Hence it is the correct option.

Explanation for incorrect answer:-

Option (A) Starch and nylon

• Nylon is a synthetic polymer that is prepared by the condensation polymerisation of hexamethylenediamine with adipic acid which happens at high temperature as well as high pressure.
• Starch is a natural polymer.
• One of the methods of preparing a synthetic polymer called Nylon 6 6 is:

• Hence it is the incorrect option.

Option (C) Proteins and nylon

• Nylon is a synthetic polymer that is prepared by the condensation polymerisation of hexamethylenediamine with adipic acid which happens at high temperature as well as high pressure.
• Protein is a natural polymer.
• One of the methods of preparing a synthetic polymer called Nylon 6 6 is:

• Hence it is the incorrect option.

Option (D) Proteins and PVC

• Protein is a natural polymer.
• Poly vinyl chloride(PVC) is a synthetic polymer that is made from vinyl chloride.
• Hence it is the incorrect option.

Therefore, option (B) is the correct answer.
