Arrange water, ethanol and phenol in increasing order of acidity and give reason for your answer.

Explanation

To arrange water, ethanol, and phenol in increasing order of acidity, we need to analyze the stability of their conjugate bases after the removal of a proton (H⁺). Here’s a step-by-step solution:

### Step 1: Understand Acidity
Acidity is defined by how easily a compound can donate a proton (H⁺). The more stable the conjugate base formed after the proton is removed, the stronger the acid.

### Step 2: Draw Structures
- **Water (H₂O)**: The structure is H-O-H.
- **Ethanol (C₂H₅OH)**: The structure is CH₃-CH₂-OH.
