Which acid of each pair shown here would you expect to be stronger ? `CH_(2)FCO_(2)H or CH_(2)CICO_(2)H`

Explanation

To determine which acid is stronger between `CH₂FCO₂H` (fluoroacetic acid) and `CH₂ClCO₂H` (chloroacetic acid), we need to analyze the effects of the substituents (fluorine and chlorine) on the acidity of the carboxylic acids.

### Step-by-Step Solution:

1. **Identify the Structure of the Acids**:
- Fluoroacetic acid: `CH₂FCO₂H`
- Chloroacetic acid: `CH₂ClCO₂H`
