A solution of Benzyl chloride, Benzoic acid and Aniline was extracted initially with a HCl solution of to give fraction A. The left over organic phase was extracted with conc. NaOH solution to give fraction B. The final organic layer was labelled as fraction A, B and C contain respectively

Options

A. Benzoic acid, Benzyl chloride and aniline
B. Aniline, Benzoic acid and Benzyl chloride
C. Benzyl chloride, Benzoic acid and aniline
D. Aniline, Benzyl chloride and Benzoic acid

Explanation

To solve the problem, we need to analyze the extraction process step by step.

### Step 1: Identify the Components
We have three compounds in the solution:
1. Benzyl chloride (C6H5CH2Cl)
2. Benzoic acid (C6H5COOH)
3. Aniline (C6H5NH2)

### Step 2: First Extraction with HCl
The solution is first extracted with HCl. Since HCl is an acid, it will react with basic compounds. Among the three components, aniline is the only basic compound. Therefore, aniline will react with HCl to form a soluble salt (anilinium chloride).

- **Fraction A**: This will contain the aniline salt (anilinium chloride).

### Step 3: Remaining Organic Phase
After the extraction of aniline, we are left with the organic phase containing benzyl chloride and benzoic acid.

### Step 4: Second Extraction with Concentrated NaOH
The leftover organic phase is then extracted with concentrated NaOH. Benzoic acid is a weak acid and will react with NaOH to form a soluble salt (sodium benzoate). Benzyl chloride, being neutral, will not react with NaOH and will remain in the organic phase.

- **Fraction B**: This will contain the sodium benzoate (the salt of benzoic acid).
- **Fraction C**: This will contain benzyl chloride, which does not react with NaOH.

### Conclusion
Now we can summarize the contents of the fractions:
- **Fraction A**: Aniline (as anilinium chloride)
- **Fraction B**: Benzoic acid (as sodium benzoate)
- **Fraction C**: Benzyl chloride

Thus, the final answer is:
- **Fraction A**: Aniline
- **Fraction B**: Benzoic acid
- **Fraction C**: Benzyl chloride

### Final Answer
The fractions A, B, and C contain respectively: **Aniline, Benzoic Acid, and Benzyl Chloride**.
