Assertion (A): Cellulose is used in making shatter- proof glass. Reason (R): Polysaccharides are not soluble in water.Codes:
✓ Correct answer: a) Both ‘A’ and ‘R’ are individually true and ‘R’ is the correct explanation of’ A’ .
ExplanationCellulose is a natural polysaccharide and the primary structural component of plant cell walls, providing strength and rigidity.It is widely used in industries for making paper, textiles, and derivatives like cellulose acetate and cellulose nitrate for various applications.Assertion (A) is true: Cellulose acetate, derived from cellulose, is used in the manufacture of shatterproof plastics, including glass used for eyewear and safety applications.These derivatives provide durability and impact resistance, essential for safety applications.Reason (R) is true: Polysaccharides such as cellulose are not soluble in water due to their extensive hydrogen bonding and crystalline structure.This insolubility is a key property of cellulose, which contributes to its stability and strength when used in manufacturing materials like shatterproof glass.Hence, Reason (R) provides the correct explanation of Assertion (A).385
