Oxidation state exhibited by Cl in `HClO` is

Answer

To find the oxidation state of chlorine (Cl) in hypochlorous acid (HClO), we can follow these steps:

### Step 1: Write the formula for the compound
The compound in question is hypochlorous acid, which has the formula HClO.

### Step 2: Assign oxidation states to known elements
- The oxidation state of hydrogen (H) is +1.
- The oxidation state of oxygen (O) is typically -2.

### Step 3: Set up the equation for the oxidation states
In the compound HClO, we can represent the oxidation state of chlorine as \( x \). The overall charge of the molecule is neutral (0). Therefore, we can set up the equation based on the oxidation states:

\[ \text{Oxidation state of H} + \text{Oxidation state of Cl} + \text{Oxidation state of O} = 0 \]

Substituting the known values into the equation, we have:

\[ (+1) + x + (-2) = 0 \]

### Step 4: Simplify the equation
Now, we simplify the equation:

\[ 1 + x - 2 = 0 \]

This simplifies to:

\[ x - 1 = 0 \]

### Step 5: Solve for \( x \)
Now, we can solve for \( x \):

\[ x = 1 \]

### Conclusion
The oxidation state of chlorine in hypochlorous acid (HClO) is +1.
