Boron trichloride on reaction with water produces 'X' along with `HCl 'X'` is.

Options

A. `BOCl_(3)`
B. `B_(2)H_(6)`
C. `B(OH)_(3)`
D. `B_(2)O_(3)`

Explanation

To solve the question regarding the reaction of boron trichloride (BCl3) with water (H2O) and to identify the product 'X' formed along with hydrochloric acid (HCl), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in the reaction are boron trichloride (BCl3) and water (H2O).

2. **Write the Reaction**: When boron trichloride reacts with water, the chemical reaction can be represented as:
\[ \text{BCl}_3 + \text{H}_2\text{O} \rightarrow \text{X} + \text{HCl} \]

3. **Determine the Product 'X'**: In the reaction, boron trichloride reacts with water to form boron hydroxide. The chemical formula for boron hydroxide is:
\[ \text{B(OH)}_3 \]
Therefore, 'X' is boron hydroxide (B(OH)3).

4. **Complete the Reaction Equation**: The complete balanced reaction can be written as:
\[ \text{BCl}_3 + 3\text{H}_2\text{O} \rightarrow \text{B(OH)}_3 + 3\text{HCl} \]

5. **Conclusion**: From the above reaction, we conclude that 'X' is boron hydroxide (B(OH)3).

### Final Answer:
Thus, the product 'X' formed along with HCl when boron trichloride reacts with water is **Boron hydroxide (B(OH)3)**.
