Which is not true above white phosphorus?

Options

A. 6 P - P single bods
B. 4 P - P single bonds
C. 4 long pair of electrons
D. P - P - P angle of `60^@`

Answer

To solve the question "Which is not true about white phosphorus?" we need to analyze the properties and structure of white phosphorus (P4) and evaluate the given options. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Structure of White Phosphorus
- White phosphorus consists of four phosphorus atoms arranged in a tetrahedral geometry.
- The molecular formula is P4.

**Hint:** Remember that the structure of white phosphorus is crucial for understanding its properties.

### Step 2: Analyze the Bonding
- In white phosphorus, each phosphorus atom is bonded to three other phosphorus atoms through single bonds.
- This results in a total of 6 P-P single bonds in the P4 molecule.

**Hint:** Focus on the type of bonds and the number of bonds in the structure.

### Step 3: Determine the Bond Angles
- The bond angles in white phosphorus are approximately 60 degrees due to its tetrahedral structure.

**Hint:** Consider how the tetrahedral arrangement affects bond angles.

### Step 4: Count the Lone Pairs
- Each phosphorus atom in white phosphorus has one lone pair of electrons, leading to a total of 4 lone pairs in the entire molecule.

**Hint:** Remember that lone pairs can influence the reactivity and properties of the molecule.

### Step 5: Evaluate the Options
- Now, we need to evaluate the provided options (A, B, C, D) to identify which statement is not true about white phosphorus based on our analysis.
- After reviewing the properties:
- 6 P-P single bonds: True
- 4 lone pairs: True (1 lone pair per phosphorus atom)
- P-P bond angle of 60 degrees: True
- Any other statement that contradicts these facts would be the incorrect one.

**Hint:** Compare each option against the established facts about white phosphorus.

### Conclusion
After analyzing the structure, bonding, angles, and lone pairs of white phosphorus, we conclude that the statement in option B (or whichever option is identified as incorrect) is not true about white phosphorus.

### Final Answer
The option that is not true about white phosphorus is **Option B**.
