Among the following sets of reactants which one produces anisole?

Options

A. `CH_(3) CHO,RMgX`
B. `C_(6)H_(5)OH,NaOH,CH_(3)l`
C. `C_(6)H_(5)OH, " netural "FeCl_(3)`
D. `C_(6)H_(5)-CH_(3),CH_(3)COCl,AlCl_(3)`

Answer

To determine which set of reactants produces anisole, we need to analyze the given options step by step.

### Step 1: Understand the Structure of Anisole
Anisole is an aromatic ether with the chemical formula C₇H₈O. Its structure consists of a phenyl group (C₆H₅) attached to a methoxy group (–OCH₃).

### Step 2: Analyze Each Set of Reactants
1. **Acetaldehyde with Grignard Reagent**:
- When acetaldehyde (CH₃CHO) reacts with a Grignard reagent (like CH₃MgBr), it forms a secondary alcohol after hydrolysis. This does not lead to anisole.

2. **Phenol with Methyl Iodide and NaOH**:
- In this reaction, phenol (C₆H₅OH) reacts with methyl iodide (CH₃I) in the presence of sodium hydroxide (NaOH). The hydroxyl group of phenol is replaced by a methyl group, forming anisole (C₆H₅OCH₃) and sodium iodide (NaI) as a byproduct. This is indeed the formation of anisole.

3. **Phenol with Nitrobenzene Chloride**:
- This reaction involves phenol and nitrophenyl chloride, which does not lead to the formation of anisole. Instead, it forms a complex and does not yield the desired ether.

4. **Toluene with Acyl Chloride in the Presence of AlCl₃**:
- This is a Friedel-Crafts acylation reaction. It leads to the formation of ketones rather than ethers, specifically acetophenone, and does not yield anisole.

### Step 3: Conclusion
From the analysis above, the only set of reactants that produces anisole is the second one: **Phenol, Methyl Iodide, and NaOH**. Therefore, the correct answer is option B.

### Final Answer
**Option B: Phenol, CH₃I, and NaOH produces anisole.**
