Hydrolysis of `NCl_3` gives `NH_3` and `X`. Which of the following is `X` ?

Options

A. `HClO_4`
B. `HClO_3`
C. `HOCl`
D. `HClO_2`

Explanation

To solve the problem of identifying the product \( X \) in the hydrolysis of \( NCl_3 \), we can follow these steps:

### Step 1: Write the hydrolysis reaction
The hydrolysis of nitrogen trichloride (\( NCl_3 \)) with water (\( H_2O \)) can be represented as:
\[ NCl_3 + H_2O \rightarrow NH_3 + X \]

### Step 2: Identify the products
From the hydrolysis of \( NCl_3 \), we know that one of the products is ammonia (\( NH_3 \)). We need to determine what \( X \) is.

### Step 3: Determine the other product
The hydrolysis of \( NCl_3 \) typically produces hypochlorous acid (\( HOCl \)). Therefore, we can write:
\[ NCl_3 + H_2O \rightarrow NH_3 + HOCl \]

### Step 4: Balance the reaction
To ensure the reaction is balanced, we can multiply the reactants and products appropriately. The balanced equation can be represented as:
\[ NCl_3 + 3H_2O \rightarrow NH_3 + 3HOCl \]

### Step 5: Identify \( X \)
From the balanced equation, we see that \( X \) is \( HOCl \) (hypochlorous acid).

### Conclusion
Thus, the product \( X \) formed from the hydrolysis of \( NCl_3 \) is \( HOCl \).

### Final Answer
The answer is \( HOCl \).
