Wrong statement regarding white phosphorus `(P_4)` is:

Options

A. it has six P - P single bonds
B. it has four P - P single bonds
C. it has four lone pair of electrons
D. bond angle around phosphorus is `60^(@)`

Answer

To determine the wrong statement regarding white phosphorus (P₄), we need to analyze the properties and structure of white phosphorus.

### Step-by-Step Solution:

1. **Understanding the Structure of White Phosphorus (P₄)**:
- White phosphorus consists of four phosphorus atoms arranged in a tetrahedral structure. Each phosphorus atom is bonded to the other three phosphorus atoms.

**Hint**: Recall the molecular geometry of P₄ and how the phosphorus atoms are arranged.

2. **Identifying the Bonding**:
- Each phosphorus atom in P₄ has five valence electrons (3s² 3p³). In forming bonds, three of these electrons participate in bonding with other phosphorus atoms, while two electrons remain as lone pairs.

**Hint**: Consider the electron configuration of phosphorus and how it contributes to bonding.

3. **Counting the Bonds**:
- In the tetrahedral structure of P₄, each phosphorus atom forms three single bonds with the other phosphorus atoms. Therefore, the total number of P-P bonds in P₄ is six (since each bond is counted twice, once for each atom).

**Hint**: Visualize the tetrahedral structure and count the bonds carefully.

4. **Analyzing the Statements**:
- **Statement 1**: "It has 6 P-P single bonds." - This statement is correct.
- **Statement 2**: "It has 4 P-P single bonds." - This statement is incorrect because there are actually 6 P-P bonds.
- **Statement 3**: "It has 4 lone pairs." - This statement is correct as each of the four phosphorus atoms has one lone pair.
- **Statement 4**: "The bond angle around phosphorus is 60 degrees." - This statement is also correct; the bond angles in P₄ are approximately 60 degrees.

**Hint**: Compare each statement against the known properties of P₄.

5. **Conclusion**:
- The wrong statement regarding white phosphorus (P₄) is that it has 4 P-P single bonds. The correct number of P-P single bonds is 6.

### Final Answer:
The wrong statement regarding white phosphorus (P₄) is: "It has 4 P-P single bonds."
