D. `HClO_(3) gt HClO_(2) gt HClO_(4) gt HOCl`

Answer

To analyze the relative acidic strength, stability, and oxidizing ability of the oxyacids of chlorine, we can follow these steps:

### Step 1: Understand the Oxyacids of Chlorine
The oxyacids of chlorine include:
- HClO (Hypochlorous acid)
- HClO2 (Chlorous acid)
- HClO3 (Chloric acid)
- HClO4 (Perchloric acid)

### Step 2: Determine Acidic Strength
The acidic strength of oxyacids generally increases with the oxidation state of chlorine. As the oxidation number of chlorine increases, the ability of the acid to donate protons (H⁺) also increases. The order of acidic strength is:
- HClO < HClO2 < HClO3 < HClO4

### Step 3: Analyze Stability of Conjugate Bases
The stability of the conjugate bases is inversely related to the strength of the acid. A stronger acid has a weaker conjugate base. The conjugate bases of these acids are:
- ClO⁻ (from HClO)
- ClO2⁻ (from HClO2)
- ClO3⁻ (from HClO3)
- ClO4⁻ (from HClO4)

The order of stability of the conjugate bases is:
- ClO⁻ < ClO2⁻ < ClO3⁻ < ClO4⁻

### Step 4: Relate Acidic Strength to Oxidizing Ability
The oxidizing ability of these acids also increases with the oxidation state of chlorine. Higher oxidation states correspond to stronger oxidizing agents. Therefore, the order of oxidizing ability is the same as the order of acidic strength:
- HClO < HClO2 < HClO3 < HClO4

### Step 5: Summarize Findings
- **Acidic Strength**: HClO < HClO2 < HClO3 < HClO4
- **Stability of Conjugate Bases**: ClO⁻ < ClO2⁻ < ClO3⁻ < ClO4⁻
- **Oxidizing Ability**: HClO < HClO2 < HClO3 < HClO4

### Final Answer
The relative acidic strength, stability, and oxidizing ability of the oxyacids of chlorine are as follows:
- Acidic strength: HClO < HClO2 < HClO3 < HClO4
- Stability of conjugate bases: ClO⁻ < ClO2⁻ < ClO3⁻ < ClO4⁻
- Oxidizing ability: HClO < HClO2 < HClO3 < HClO4
