Oxyacid formed when `NCl_(3)` is hydrolysed is

Options

A. `HOCl`
B. `HClO_(2)`
C. `HClO_(4)`
D. None of these

Answer

To determine the oxyacid formed when nitrogen trichloride (NCl₃) is hydrolyzed, we can follow these steps:

### Step 1: Understand Hydrolysis
Hydrolysis is a chemical reaction involving the addition of water (H₂O) to a compound, leading to the formation of new substances. In this case, we are hydrolyzing nitrogen trichloride (NCl₃).

**Hint:** Hydrolysis typically involves water breaking down a compound into its components.

### Step 2: Write the Hydrolysis Reaction
When NCl₃ is hydrolyzed, it reacts with water. The general reaction can be written as:
\[ \text{NCl}_3 + \text{H}_2\text{O} \rightarrow \text{HOCl} + \text{NH}_3 + \text{HCl} \]

**Hint:** Look for the products that are formed when water interacts with the compound.

### Step 3: Identify the Oxyacid
From the hydrolysis reaction, one of the products formed is hypochlorous acid (HOCl). An oxyacid is defined as an acid that contains oxygen bonded to hydrogen.

**Hint:** An oxyacid must have at least one oxygen atom bonded to a hydrogen atom.

### Step 4: Confirm the Structure of Hypochlorous Acid
Hypochlorous acid (HOCl) has the structure where one oxygen atom is bonded to one hydrogen atom and also bonded to a chlorine atom. This confirms that it is indeed an oxyacid.

**Hint:** Check the structure of the acid to ensure it meets the criteria of an oxyacid.

### Step 5: Conclusion
Thus, the oxyacid formed when NCl₃ is hydrolyzed is hypochlorous acid (HOCl).

**Final Answer:** HOCl
