Valency factor of the following compounds will be same in neutralisation -

Options

A. `SO_(2) rarr H_(2)SO_(3)`
B. `NH_(3)+H^(+)rarr NH_(4)^(+)`
C. `N_(2)O_(6) rarr 2HNO_(3)`
D. `A` and `C` have same valency factor

Explanation

To determine the valency factor of the given compounds in neutralization, we need to analyze how many protons (H⁺ ions) each compound can accept or donate during the reaction. The valency factor (n) is defined as the number of moles of H⁺ ions that can be accepted or donated by one mole of the substance in a neutralization reaction.

### Step-by-Step Solution:

1. **Analyze the first compound: SO₂ (Sulfur Dioxide)**
- Reaction: SO₂ + 2H₂O → H₂SO₃ (Sulfurous Acid)
- In this reaction, SO₂ accepts 2 protons (H⁺ ions) to form H₂SO₃.
- Therefore, the valency factor (n) for SO₂ is **2**.

2. **Analyze the second compound: NH₃ (Ammonia)**
- Reaction: NH₃ + H⁺ → NH₄⁺ (Ammonium Ion)
- In this reaction, NH₃ accepts 1 proton (H⁺ ion) to form NH₄⁺.
- Therefore, the valency factor (n) for NH₃ is **1**.

3. **Analyze the third compound: N₂O₆ (Dinitrogen Hexoxide)**
- Reaction: N₂O₆ + 6H₂O → 6HNO₃ (Nitric Acid)
- In this reaction, N₂O₆ accepts 2 protons (H⁺ ions) to form HNO₃.
- Therefore, the valency factor (n) for N₂O₆ is **2**.

4. **Conclusion:**
- The valency factors calculated are:
- SO₂: 2
- NH₃: 1
- N₂O₆: 2
- From the analysis, we can see that the valency factors of SO₂ and N₂O₆ are the same (both are 2), while NH₃ has a different valency factor (1).

### Final Answer:
The valency factors of SO₂ and N₂O₆ will be the same in neutralization, both being **2**.
