Why is dichloroacetic acid stronger than monochloroacetic acid ?

Explanation

To understand why dichloroacetic acid is stronger than monochloroacetic acid, we need to analyze the structures and the stability of their conjugate bases. Here’s a step-by-step breakdown of the explanation:

### Step 1: Draw the Structures
- **Dichloroacetic Acid**: This acid has two chlorine atoms attached to the acetic acid structure.
- **Monochloroacetic Acid**: This acid has one chlorine atom attached to the acetic acid structure.

### Step 2: Remove the Acetic Hydrogen
- When we consider the acidic nature of these compounds, we need to remove the acidic hydrogen (the hydrogen atom attached to the carboxylic group, -COOH) to form their conjugate bases.
