Which of the following is most acidic molecule?

Options

A. `CH_(3)- NO_(2)`
B. `(CH_(3))_(2) CH-NO_(2)`
C. `(NO_(2))_(3)C-H`
D. `CH_(3) -CH_(2) -NO_(2)`

Explanation

To determine which of the given molecules is the most acidic, we need to analyze the structures and the effects of the substituents on acidity. Let's break it down step by step.

### Step 1: Identify the Molecules
We have four molecules to analyze:
1. **A:** CH3NO2 (Nitromethane)
2. **B:** CH3CH(NO2)CH3 (Nitropropane)
3. **C:** CH(NO2)3 (Trinitromethane)
4. **D:** CH3CH2NO2 (Nitroethane)
