The correct Answer is:
To solve the question of matching the items in List-I with those in List-II, we will analyze each item in List-I and identify its corresponding item in List-II based on their chemical names and structures. ### Step-by-Step Solution: 1. **Identify Wood Spirit**: - Wood spirit is commonly known as **Methyl alcohol**. - Chemical formula: CH₃OH. - **Match**: P (Wood spirit) matches with 2 (Methyl alcohol). 2. **Identify Absolute Alcohol**: - Absolute alcohol refers to **Ethyl alcohol**. - Chemical formula: CH₃CH₂OH. - **Match**: Q (Absolute alcohol) matches with 1 (Ethyl alcohol). 3. **Identify Glycerin**: - Glycerin is a triol, meaning it has three hydroxyl (OH) groups. - Its IUPAC name is **1,2,3-Trihydroxy propane**. - Structure: CH₂(OH)–CHOH–CH₂(OH). - **Match**: R (Glycerin) matches with 4 (1,2,3-Trihydroxy propane). 4. **Identify Glycol**: - Glycol is a diol, meaning it has two hydroxyl (OH) groups. - Its IUPAC name is **1,2-Dihydroxyethane**. - Structure: CH₂(OH)–CH₂(OH). - **Match**: S (Glycol) matches with 3 (1,2-Dihydroxyethane). ### Final Matches: - P (Wood spirit) → 2 (Methyl alcohol) - Q (Absolute alcohol) → 1 (Ethyl alcohol) - R (Glycerin) → 4 (1,2,3-Trihydroxy propane) - S (Glycol) → 3 (1,2-Dihydroxyethane) ### Conclusion: The correct matches are: - P → 2 - Q → 1 - R → 4 - S → 3
