Question

Match the entries in Group I with the entries in Group II 

• A. P-iv, Q-i, R-ii, S-iii
• B. P-iv, Q-i, R-iii, S-ii
• C. P-iv, Q-iii, R-i, S-i
• D. P-ii, Q-iv, R-i, S-iii

Hint:

When matching items, focus on understanding the origin or structure of the compounds or materials. For example, natural rubber is made from isoprene, and myoglobin is composed of amino acids.

Answer 1

The Correct Option is A

Step 1: Analyzing the pairs.
- Nylon (P) is a polymer, typically derived from adipic acid and hexamethylenediamine, matching with (iv) Adipic acid.
- Natural rubber (Q) is derived from isoprene, matching with (i) Isoprene.
- Starch (R) is a polysaccharide made up of hexose units, matching with (ii) Hexose.
- Myoglobin (S) is a protein composed of amino acids, matching with (iii) Amino acid.
Step 2: Conclusion.
The correct matching is (A) P-iv, Q-i, R-ii, S-iii.
