Q25ScienceChemistry in Everyday LifePYQ 2006

Assertion (A): Cellulose is used in making shatter-proof glass. Reason (R): Polysaccharides are not soluble in water. Select the correct answer.

  • ABoth A and R are individually true and R is the correct explanation of A
  • BBoth A and R are individually true but R is not the correct explanation of ACorrect
  • CA is true but R is false
  • DA is false but R is true

Explanation

Correct. Cellulose derivatives (like cellulose acetate) are used as interlayers in laminated safety glass. Polysaccharides being water-insoluble is true but is not the reason cellulose is used in glass.

Why the other options are incorrect
Option A

While both statements are true, cellulose is used in shatter-proof glass because of its transparent film-forming property when processed as cellulose acetate, not because polysaccharides are water-insoluble.

Option C

R is true — most polysaccharides (cellulose, starch) are indeed insoluble or poorly soluble in water.

Option D

A is also true; cellulose acetate interlayers are used in the manufacture of safety/shatter-proof glass.
