A solution of Benzylamine, Cyclohexanol and Picric acid in ethyl acetate was extracted initially with a saturated solution of `NaHCO_(3)` to give fraction A. The left over organic phase was extracted with chloroform with KOH give fraction B. The final organic layer was labelled as fraction C.
Fractions A, B and C contain respectively :

Options

A. Picric acid, Benzylamine, Cyclohexanol
B. Benzylamine, Picric acid, Cyclohexanol
C. Picric acid, Cyclohexanol, Benzylamine
D. Benzylamine, Cyclohexanol, Picric acid

Explanation

To solve the problem, we need to analyze the extraction process step by step, identifying which compounds are present in each fraction (A, B, and C).

### Step 1: Identify the Compounds
The compounds involved in the extraction are:
1. Benzylamine (C6H5CH2NH2) - a weak base.
2. Cyclohexanol (C6H11OH) - a neutral alcohol.
3. Picric acid (2,4,6-trinitrophenol) - a strong acid due to the presence of three nitro groups.

### Step 2: Extraction with NaHCO3
The first extraction is done using a saturated solution of sodium bicarbonate (NaHCO3). Since NaHCO3 is a weak base, it will react with the acidic component in the solution.

- **Picric acid** is the only acidic compound among the three. It will react with NaHCO3 to form the soluble sodium picrate and release carbon dioxide (CO2) and water.
- **Benzylamine** and **Cyclohexanol** do not react with NaHCO3 because they are not acidic enough.

**Result of Step 2:**
- **Fraction A** contains sodium picrate (soluble in water).
- **Leftover organic phase** contains Benzylamine and Cyclohexanol.

### Step 3: Extraction with Chloroform and KOH
The leftover organic phase (Benzylamine and Cyclohexanol) is then extracted with chloroform (CHCl3) in the presence of potassium hydroxide (KOH).

- **Benzylamine**, being a weak base, can react with KOH. In this case, KOH will deprotonate benzylamine, allowing it to form a soluble salt.
- **Cyclohexanol** is neutral and does not react with KOH.

**Result of Step 3:**
- **Fraction B** will contain the salt of Benzylamine (phenyl isocyanide).
- **Fraction C** will contain Cyclohexanol, which remains unreacted and is not soluble in KOH.

### Final Summary of Fractions
- **Fraction A**: Contains **Picric acid** (sodium picrate).
- **Fraction B**: Contains **Benzylamine** (as a salt).
- **Fraction C**: Contains **Cyclohexanol**.

### Conclusion
The fractions contain:
- **Fraction A**: Picric acid
- **Fraction B**: Benzylamine
- **Fraction C**: Cyclohexanol
