White phosphorus `(P_4)` does not contain

Options

A. six P-P single bonds
B. four P-P single bonds
C. four lone pairs of electrons
D. P-P-P angle of `60^@`

Answer

To solve the question of what White Phosphorus `(P_4)` does not contain, we will analyze the structure and bonding of White Phosphorus step by step.

### Step 1: Understanding the Structure of White Phosphorus
White Phosphorus is represented by the molecular formula `P_4`. This indicates that it consists of four phosphorus atoms.

**Hint:** Remember that the molecular formula gives you the number of atoms present in the molecule.

### Step 2: Analyzing the Bonding
In `P_4`, the four phosphorus atoms are arranged in a tetrahedral shape. Each phosphorus atom is bonded to three other phosphorus atoms through single bonds.

**Hint:** Visualize the tetrahedral arrangement to understand how the atoms are connected.

### Step 3: Counting the Bonds
In the structure of `P_4`, there are a total of 6 phosphorus-phosphorus (P-P) single bonds. This can be confirmed by counting the bonds formed between the phosphorus atoms in the tetrahedral structure.

**Hint:** Count the number of bonds carefully to ensure accuracy.

### Step 4: Evaluating the Lone Pairs
Each phosphorus atom has 5 valence electrons. After forming bonds with other phosphorus atoms, each atom will have one lone pair of electrons remaining. Since there are 4 phosphorus atoms, this results in a total of 4 lone pairs of electrons.

**Hint:** Remember that lone pairs are non-bonding pairs of electrons that remain after bonding.

### Step 5: Analyzing the Options
Now, we need to determine which of the given options is not present in `P_4`. The options typically include:
1. 6 P-P single bonds
2. 4 P-P single bonds
3. 4 lone pairs of electrons
4. P-P-P bond angle of 60 degrees

From our analysis:
- There are indeed 6 P-P single bonds.
- There are not 4 P-P single bonds (this is incorrect).
- There are 4 lone pairs of electrons.
- The P-P-P bond angle is not 60 degrees; it is actually around 60 degrees due to the tetrahedral arrangement.

### Conclusion
The correct answer to the question "White phosphorus `(P_4)` does not contain" is **4 P-P single bonds**.

**Final Answer:** White phosphorus `(P_4)` does not contain 4 P-P single bonds.
