The correct Answer is:
To solve the problem of matching the common names of alcohols and their corresponding chemical names, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Common Names**: - We have four common names: Wood Spirit, Absolute Alcohol, Glycerine, and Glycerol. 2. **Match Wood Spirit**: - Wood Spirit is the common name for **Methyl Alcohol** (Methanol). - Therefore, we can match: - **P → (2) Methyl Alcohol** 3. **Match Absolute Alcohol**: - Absolute Alcohol is commonly known as **Ethyl Alcohol** (Ethanol). - Thus, we can match: - **Q → (1) Ethyl Alcohol** 4. **Match Glycerine**: - Glycerine is also known as **Glycerol**, which is a compound with three hydroxyl groups. - The chemical name for Glycerine is **1,2,3-Trihydroxypropane**. - Therefore, we can match: - **R → (4) 1,2,3-Trihydroxypropane** 5. **Match Glycerol**: - Glycerol is the same as Glycerine and is also represented by the chemical name **1,2-Dihydroxyethane** (which is actually ethylene glycol). - However, since we have already matched Glycerine, we can conclude: - **S → (3) 1,2-Dihydroxyethane** ### Final Matches: - P → (2) Methyl Alcohol - Q → (1) Ethyl Alcohol - R → (4) 1,2,3-Trihydroxypropane - S → (3) 1,2-Dihydroxyethane ### Answer: The correct matching is: - P = 2 - Q = 1 - R = 4 - S = 3 Thus, the answer is option number 3. ---
