`CH_(3)COOH` is weaker acid than `H_(2)SO_(4)`. It is due to

Options

A. More ionisation
B. Less ionisation
C. Covalent bond
D. Electrovalent bond

Explanation

To determine why CH₃COOH (acetic acid) is a weaker acid than H₂SO₄ (sulfuric acid), we can analyze the properties of both acids in terms of their ionization in water.

### Step-by-Step Solution:

1. **Definition of Weak and Strong Acids**:
- A weak acid is one that partially dissociates into ions in an aqueous solution. In contrast, a strong acid completely dissociates into ions when dissolved in water.

2. **Ionization of Acetic Acid (CH₃COOH)**:
- When acetic acid is dissolved in water, it ionizes as follows:
\[ \text{CH}_3\text{COOH} \rightleftharpoons \text{CH}_3\text{COO}^- + \text{H}^+ \]
- This reaction shows that acetic acid produces one hydrogen ion (H⁺) and one acetate ion (CH₃COO⁻). This indicates that acetic acid has a limited degree of ionization.

3. **Ionization of Sulfuric Acid (H₂SO₄)**:
- Sulfuric acid, on the other hand, ionizes in two steps:
\[ \text{H}_2\text{SO}_4 \rightarrow \text{H}^+ + \text{HSO}_4^- \]
\[ \text{HSO}_4^- \rightleftharpoons \text{H}^+ + \text{SO}_4^{2-} \]
- In the first step, sulfuric acid produces one hydrogen ion (H⁺) and one hydrogen sulfate ion (HSO₄⁻). In the second step, the hydrogen sulfate ion can further dissociate to produce another hydrogen ion (H⁺) and a sulfate ion (SO₄²⁻). Thus, sulfuric acid can produce a total of two hydrogen ions.

4. **Comparison of Ionization**:
- Since H₂SO₄ can produce more hydrogen ions (two) compared to CH₃COOH (one), it indicates that H₂SO₄ has a higher degree of ionization than CH₃COOH.
- The greater the number of hydrogen ions produced, the stronger the acid. Therefore, H₂SO₄ is a strong acid, while CH₃COOH is a weak acid.

5. **Conclusion**:
- The reason CH₃COOH is a weaker acid than H₂SO₄ is due to its **less ionization** in water compared to sulfuric acid.

### Final Answer:
CH₃COOH is a weaker acid than H₂SO₄ due to **less ionization**.
