D. 1, 2

Answer

To determine the number of peroxide linkages in \( \text{CrO}_5 \) and \( \text{H}_2\text{SO}_5 \), we will analyze the structures of both compounds step by step.

### Step 1: Understanding Peroxide Linkages
Peroxide linkages are defined as the presence of an oxygen-oxygen single bond (O-O). In chemical structures, these linkages can be identified by looking for pairs of oxygen atoms connected by a single bond.

### Step 2: Analyzing \( \text{CrO}_5 \)
1. **Structure of \( \text{CrO}_5 \)**:
- \( \text{CrO}_5 \) can be represented as having one chromium atom bonded to five oxygen atoms.
- The structure can be visualized as \( \text{Cr} = \text{O} \) (double bond) and two \( \text{O-O} \) linkages.

2. **Identifying Peroxide Linkages**:
- In the structure of \( \text{CrO}_5 \), we have two oxygen atoms connected by single bonds (O-O).
- Thus, we have **2 peroxide linkages** in \( \text{CrO}_5 \).

### Step 3: Analyzing \( \text{H}_2\text{SO}_5 \)
1. **Structure of \( \text{H}_2\text{SO}_5 \)**:
- \( \text{H}_2\text{SO}_5 \) is known as peroxymonosulfuric acid (or Caro's acid).
- The structure can be represented as: \( \text{O} = \text{S} = \text{O} \) (double bond), \( \text{OH} \), \( \text{O-O} \), and another \( \text{OH} \).

2. **Identifying Peroxide Linkages**:
- In the structure of \( \text{H}_2\text{SO}_5 \), there is one oxygen-oxygen single bond (O-O).
- Thus, we have **1 peroxide linkage** in \( \text{H}_2\text{SO}_5 \).

### Conclusion
- The number of peroxide linkages in \( \text{CrO}_5 \) is **2**.
- The number of peroxide linkages in \( \text{H}_2\text{SO}_5 \) is **1**.

Therefore, the final answer is:
- **2 and 1** respectively for \( \text{CrO}_5 \) and \( \text{H}_2\text{SO}_5 \).
