The naturally occurring polymer among the following is:

  1. Rayon
  2. Nylon - $6$

  3. Decron

  4. Proteins
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

NATURAL  POLYMER  -  The polymers found in nature, i.e., from plants & animals are known as natural polymers.
RAYON - Rayon is classified as semisynthetic polymer, as it is manufactured from naturally occuring polymers. It is purified from cellulose.
NYLON - $6$  -  Nylon - $6$ is a synthetic polymer, obtained by heating caprolactum with water at high temp.
DACRON  -  It is also a synthetic polymer. It is formed by interaction of ethylene glycol & terephthalic acid.
PROTEINS  -  Proteins are large macromolecules, containing one or more chains of amino acids. They are held together by peptide bonds. Amino acids are found in living organisms. Hence, they are natural polymer.
