Explanation

To determine the correct order of acidic nature of nitrogen oxides, we need to analyze the oxidation states of nitrogen in each oxide. The acidic nature of oxides generally increases with the oxidation state of the central atom (in this case, nitrogen). Here’s how we can derive the order step by step:

### Step 1: Identify the Oxides
The nitrogen oxides we are considering are:
- N₂O
- N₂O₃
- N₂O₄
- N₂O₅

### Step 2: Calculate the Oxidation State of Nitrogen in Each Oxide
1. **For N₂O:**
- Let the oxidation state of nitrogen be \( x \).
- The equation is: \( 2x + (-2) = 0 \)
- Solving gives: \( 2x = 2 \) → \( x = +1 \)

2. **For N₂O₃:**
- Let the oxidation state of nitrogen be \( x \).
- The equation is: \( 2x + (-6) = 0 \)
- Solving gives: \( 2x = 6 \) → \( x = +3 \)

3. **For N₂O₄:**
- Let the oxidation state of nitrogen be \( x \).
- The equation is: \( 2x + (-8) = 0 \)
- Solving gives: \( 2x = 8 \) → \( x = +4 \)

4. **For N₂O₅:**
- Let the oxidation state of nitrogen be \( x \).
- The equation is: \( 2x + (-10) = 0 \)
- Solving gives: \( 2x = 10 \) → \( x = +5 \)

### Step 3: Determine the Order of Acidic Nature
Now that we have the oxidation states:
- N₂O: +1
- N₂O₃: +3
- N₂O₄: +4
- N₂O₅: +5

The acidic nature increases with the oxidation state. Therefore, the order of acidic nature from least acidic to most acidic is:
- N₂O (least acidic)
- N₂O₃
- N₂O₄
- N₂O₅ (most acidic)

### Conclusion
The correct order of acidic nature of the oxides is:
**N₂O < N₂O₃ < N₂O₄ < N₂O₅**
