Point out the incorrect statement regarding Be (Group IIA )

Options

A. It forms an ionic carbide
B. Its carbonate decomposes on heating
C. Its halides are covalent
D. It is easily attacked by water

Explanation

To determine the incorrect statement regarding Beryllium (Be) from Group IIA, we will analyze each statement provided.

### Step-by-Step Solution:

1. **Analyze the First Statement: "It forms an ionic carbide."**
- Beryllium does indeed form an ionic carbide, specifically beryllium carbide (Be2C). This statement is **correct**.

2. **Analyze the Second Statement: "Its carbonate decomposes on heating."**
- Beryllium carbonate (BeCO3) does decompose upon heating to form beryllium oxide (BeO) and carbon dioxide (CO2). This statement is also **correct**.

3. **Analyze the Third Statement: "Its halides are covalent."**
- Beryllium halides (such as BeCl2) are indeed covalent in nature and are soluble in organic solvents. This statement is **correct**.

4. **Analyze the Fourth Statement: "It is easily attacked by water."**
- Beryllium does not react easily with water at room temperature. It forms a protective oxide layer that prevents further reaction. When it does react, it produces beryllium hydroxide and hydrogen gas, but it is not easily attacked by water. Therefore, this statement is **incorrect**.

### Conclusion:
The incorrect statement regarding Beryllium (Be) is: **"It is easily attacked by water."**
