`Be_(2)C` on hydrolysis yields

Options

A. `Be(OH)_(2)`
B. `C_(2)H_(2)`
C. `CH_(4)`
D. `C_(2)H_(6)`

Answer

To solve the question regarding the hydrolysis of beryllium carbide (Be₂C), we can follow these steps:

### Step 1: Identify the Compound
The compound in question is beryllium carbide, which has the formula Be₂C.

### Step 2: Understand the Hydrolysis Process
Hydrolysis refers to the reaction of a compound with water. In this case, we need to determine what products are formed when beryllium carbide reacts with water.

### Step 3: Write the Hydrolysis Reaction
When beryllium carbide (Be₂C) reacts with water (H₂O), the reaction can be represented as follows:

\[ \text{Be}_2\text{C} + 4 \text{H}_2\text{O} \rightarrow 2 \text{Be(OH)}_2 + \text{CH}_4 \]

### Step 4: Identify the Products
From the reaction, we can see that the products formed are:
1. Beryllium hydroxide (Be(OH)₂)
2. Methane (CH₄)

### Conclusion
Thus, the hydrolysis of beryllium carbide (Be₂C) yields beryllium hydroxide and methane gas.

### Final Answer
Beryllium hydroxide (Be(OH)₂) and methane (CH₄).
