The correct decreasing order of the acidic strength of `HClO, HClO_(2), HClO_(3),HClO_(4)` is

Explanation

To determine the correct decreasing order of acidic strength of the oxoacids \( HClO, HClO_2, HClO_3, HClO_4 \), we will follow these steps:

### Step 1: Understand the trend in acidic strength
The acidic strength of oxoacids generally increases with the increase in the oxidation state of the central atom (in this case, chlorine). This is because a higher oxidation state leads to a greater ability to stabilize the negative charge that results when the acid donates a proton (H⁺).

### Step 2: Determine the oxidation state of chlorine in each oxoacid
1. **For \( HClO \)**:
- Let the oxidation state of Cl be \( x \).
