Options

A. 3 and 3
B. 4 and 4
C. 3 and 4
D. 4 and 3

Answer

To determine the number of oxygen atoms bonded to each phosphorus atom in \( P_4O_6 \) and \( P_4O_{10} \), we can analyze the structures of these compounds.

### Step 1: Analyze the structure of \( P_4O_6 \)

1. **Molecular Formula**: The molecular formula \( P_4O_6 \) indicates that there are 4 phosphorus (P) atoms and 6 oxygen (O) atoms.
2. **Structure**: In \( P_4O_6 \), the phosphorus atoms are arranged in a tetrahedral structure. Each phosphorus atom is bonded to oxygen atoms.
3. **Bonding**: In this structure, each phosphorus atom is bonded to 1 oxygen atom through a single bond and shares a double bond with another oxygen atom.
4. **Counting**:
- Each phosphorus atom is bonded to 1 oxygen atom directly.
- The total number of oxygen atoms is 6, and since there are 4 phosphorus atoms, we can conclude that each phosphorus atom is bonded to an average of 1.5 oxygen atoms.
- However, in the case of \( P_4O_6 \), it can be seen that 3 out of the 4 phosphorus atoms are bonded to 2 oxygen atoms (one double bond and one single bond), and the last phosphorus is bonded to only one oxygen atom.

### Step 2: Analyze the structure of \( P_4O_{10} \)

1. **Molecular Formula**: The molecular formula \( P_4O_{10} \) indicates that there are 4 phosphorus atoms and 10 oxygen atoms.
2. **Structure**: In \( P_4O_{10} \), the phosphorus atoms are also arranged tetrahedrally, but with a different bonding pattern.
3. **Bonding**: Each phosphorus atom in \( P_4O_{10} \) is bonded to 4 oxygen atoms. This can be seen as each phosphorus atom forming double bonds with 4 oxygen atoms.
4. **Counting**:
- Since there are 4 phosphorus atoms and each is bonded to 4 oxygen atoms, the total number of oxygen atoms bonded to phosphorus is 4 for each phosphorus atom.

### Conclusion

- For \( P_4O_6 \): Each phosphorus atom is bonded to an average of 1.5 oxygen atoms.
- For \( P_4O_{10} \): Each phosphorus atom is bonded to 4 oxygen atoms.

Thus, the number of oxygen atoms bonded to each phosphorus atom in \( P_4O_6 \) and \( P_4O_{10} \) are respectively 1.5 and 4.

### Final Answer
- In \( P_4O_6 \): 1.5 oxygen atoms per phosphorus atom.
- In \( P_4O_{10} \): 4 oxygen atoms per phosphorus atom.
