(I) Starch
(II)Cellulose
(III) Sucrose
(IV) Glucose
(V) Natural rubber
(VI) PVC
(VII) Nylon-6
(VIII)Proteins
(IX) Amino acid
Answer:
Solution:
Explanation:
The question asks to identify the total number of compounds from the given list that are classified as Polymers.
Concept:
Identification and classification of polymers.
Solution:
A polymer is a large molecule (macromolecule) composed of many repeated smaller, chemical units called monomers, linked together.
Starch (Polymer of glucose), Cellulose (Polymer of glucose), Natural rubber (Polymer of isoprene), PVC (Polymer of vinyl chloride), Nylon-6 (Synthetic polymer of caprolactam) and Proteins (Polymer of amino acids) are all large molecules composed of repeating monomer units,
making them polymers.
Sucrose is a disaccharide (a small molecule, not a polymer). Glucose and Amino acid are monomers (building blocks) and are not polymers.
Thus, there are 6 compounds that are polymers: Starch, Cellulose, Natural rubber, PVC, Nylon-6, and Proteins.
