Which of the following is not correct about White Phosphorous (`P_(4)`) ?

Options

A. Six P-P single bonds
B. Four P-P single bonds
C. Four lone pair of electrons
D. PPP angle is 60°

Explanation

To determine which statement about white phosphorus (P₄) is not correct, we will analyze the structure and bonding of white phosphorus step by step.

### Step 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 three other phosphorus atoms.

### Step 2: Drawing the Lewis Structure
1. Each phosphorus atom has 5 valence electrons.
2. In the P₄ molecule, each phosphorus atom forms three single bonds with three other phosphorus atoms.
3. This results in a total of 6 P-P single bonds in the P₄ molecule.

### Step 3: Counting Lone Pairs
1. After forming three bonds, each phosphorus atom uses 3 of its 5 valence electrons.
2. This leaves 2 electrons, which form one lone pair on each phosphorus atom.
3. Since there are 4 phosphorus atoms, there are a total of 4 lone pairs of electrons.

### Step 4: Analyzing Bond Angles
1. In the tetrahedral arrangement of P₄, the bond angles between the P-P-P bonds are approximately 60 degrees.

### Step 5: Evaluating the Given Options
Now, let's evaluate the options provided in the question:
1. **6 P-P single bonds** - This is correct.
2. **4 P-P single bonds** - This is incorrect (there are 6 P-P bonds).
3. **4 lone pairs of electrons** - This is correct.
4. **Bond angle of 60 degrees** - This is correct.

### Conclusion
The statement that is not correct about white phosphorus (P₄) is: **"4 P-P single bonds."** The correct number of P-P bonds is 6.
