Options

A. `8 , 4`
B. 10 , 4
C. 12 , 4
D. 10 , 2

Answer

To determine the number of single and double P-O bonds in P₄O₁₀, we will follow these steps:

### Step 1: Draw the Structure of P₄O₁₀
P₄O₁₀, also known as phosphorus pentoxide, has a specific molecular structure. We need to visualize or draw the structure to identify the bonds.

### Step 2: Identify the Types of Bonds
In the structure of P₄O₁₀, phosphorus (P) atoms are bonded to oxygen (O) atoms. We need to look for:
- **Single P-O bonds**: These are bonds where one pair of electrons is shared between phosphorus and oxygen.
- **Double P-O bonds**: These are bonds where two pairs of electrons are shared between phosphorus and oxygen.

### Step 3: Count the Single P-O Bonds
After drawing the structure, we can count the number of single bonds. In the structure of P₄O₁₀:
- There are a total of **12 single P-O bonds**.

### Step 4: Count the Double P-O Bonds
Next, we will count the double bonds in the same structure:
- There are a total of **4 double P-O bonds**.

### Conclusion
Thus, the number of single and double P-O bonds in P₄O₁₀ is:
- **Single P-O bonds: 12**
- **Double P-O bonds: 4**

### Final Answer
The number of single and double P-O bonds in P₄O₁₀ respectively is **12 and 4**.
