How will you separate a mixture of o-nitrophenol and p-nitropheonol ?

Explanation

To separate a mixture of o-nitrophenol and p-nitrophenol, you can follow these steps:

### Step 1: Understand the Properties
- **Identify the compounds**: Recognize that o-nitrophenol (ortho-nitrophenol) and p-nitrophenol (para-nitrophenol) have different structural properties, which affect their physical characteristics.
- **Hydrogen bonding**: Note that o-nitrophenol has intramolecular hydrogen bonding, while p-nitrophenol has intermolecular hydrogen bonding. This difference influences their boiling points.

### Step 2: Analyze Boiling Points
- **Boiling point comparison**: Determine that o-nitrophenol has a lower boiling point due to intramolecular hydrogen bonding, while p-nitrophenol has a higher boiling point because of intermolecular hydrogen bonding.
