Match the column
`{:(A. "Methanol and ethanol", P. "lucas reagent"),(B. "Phenol and cyclohexanol" ,Q. "Sodium metal"),(C. n-"propylalcohol and tertbutyl alcohol", R. "Iodoformtest"),(D. "Methanol and diethylether", S. "Ferric chloride"):}`

Options

A. A–Q, B–S, C–P, D–R
B. A–S, B–P, C–Q, D–R
C. A–P, B–Q, C–R, D–S
D. A–R, B–S, C–P, D–Q

Answer

To solve the matching question, we will analyze each pair of compounds and their corresponding tests.

### Step-by-Step Solution:

1. **Identify the compounds in Column A**:
- A. Methanol and Ethanol
- B. Phenol and Cyclohexanol
- C. n-Propyl alcohol and tert-Butyl alcohol
- D. Methanol and Diethyl ether

2. **Identify the tests in Column P**:
- P. Lucas Reagent
- Q. Sodium Metal
- R. Iodoform Test
- S. Ferric Chloride

3. **Match each compound with the appropriate test**:
- **A. Methanol and Ethanol**: These compounds can be distinguished using the Iodoform Test (R). Ethanol gives a positive result with sodium hypochlorite, forming a yellow precipitate (iodoform).
- **B. Phenol and Cyclohexanol**: Phenol gives a positive test with Ferric Chloride (S), resulting in a colored complex.
- **C. n-Propyl alcohol and tert-Butyl alcohol**: This pair can be tested using Lucas Reagent (P). Lucas Reagent is used to differentiate between primary, secondary, and tertiary alcohols. Tert-butyl alcohol reacts quickly, while n-propyl alcohol does not.
- **D. Methanol and Diethyl ether**: This pair can be distinguished using Sodium Metal (Q). Sodium reacts with alcohols to produce hydrogen gas.

4. **Final Matches**:
- A → R (Iodoform Test)
- B → S (Ferric Chloride)
- C → P (Lucas Reagent)
- D → Q (Sodium Metal)

### Summary of Matches:
- A (Methanol and Ethanol) → R (Iodoform Test)
- B (Phenol and Cyclohexanol) → S (Ferric Chloride)
- C (n-Propyl alcohol and tert-Butyl alcohol) → P (Lucas Reagent)
- D (Methanol and Diethyl ether) → Q (Sodium Metal)

### Final Answer:
- A → R
- B → S
- C → P
- D → Q
