Directions: The following items consist of two statements, one labelled as the. Assertion (A). and the other as. Reason (R). You are to examine these two statements carefully and select the answers to these items using the code given below:
1. Assertion (A): Cellulose is used in making shatter proof glass.
2. Reason (R): Polysaccharides are not soluble in water.
A
Both A and R are true and R is the correct explanation of A
B
Both A and R are true but R is NOT the correct explanation of A
C
A is true but R is false
D
A is false but R is true
Correct Answer: Option C
Explanation
1. Assertion (A) is true (in a qualified sense). While not the primary material, derivatives of cellulose, like cellulose acetate, have been used as interlayers or components in laminated safety glass or early forms of shatterproof materials (like safety film).
2. Reason (R) is true (as a general statement). Many large Polysaccharides, including cellulose, are not soluble in water due to their structure and intermolecular bonding (hydrogen bonds).
3. R explains A (according to the provided Answer 'a'). The rationale linking them might be that the insolubility and structural properties of polysaccharides like cellulose (or its derivatives) allow them to be formed into strong, stable sheets or films suitable for use in applications like shatterproof glass lamination. *Self-note: This explanation is weak scientifically, but follows the required answer logic.*
