Answer

To determine the correct order of increasing bond angles for the given species (OF2, H2O, Cl2O, and ClO2), we will analyze the molecular structures and bond angles of each compound step by step.

### Step 1: Analyze the structure of OF2
- **Structure**: OF2 has an oxygen atom bonded to two fluorine atoms.
- **Bond Angle**: The bond angle in OF2 is approximately **103 degrees**.

### Step 2: Analyze the structure of H2O
- **Structure**: H2O consists of an oxygen atom bonded to two hydrogen atoms.
- **Bond Angle**: The bond angle in H2O is approximately **104.5 degrees**.

### Step 3: Analyze the structure of Cl2O
- **Structure**: Cl2O has an oxygen atom bonded to two chlorine atoms.
- **Bond Angle**: The bond angle in Cl2O is approximately **110.9 degrees**.

### Step 4: Analyze the structure of ClO2
- **Structure**: ClO2 has a chlorine atom double bonded to two oxygen atoms.
- **Bond Angle**: The bond angle in ClO2 is approximately **117.6 degrees**.

### Step 5: Compare the bond angles
Now we can summarize the bond angles:
- OF2: 103 degrees
- H2O: 104.5 degrees
- Cl2O: 110.9 degrees
- ClO2: 117.6 degrees

### Step 6: Order the bond angles from smallest to largest
Based on the bond angles calculated:
1. OF2: 103 degrees
2. H2O: 104.5 degrees
3. Cl2O: 110.9 degrees
4. ClO2: 117.6 degrees

Thus, the correct order of increasing bond angles is:
**OF2 < H2O < Cl2O < ClO2**

### Final Answer
The correct order of increasing bond angle is: **OF2 < H2O < Cl2O < ClO2**.
