The correct Answer is:
To determine the shape and bond angle of white phosphorus (P4), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Molecular Formula**: - The molecular formula of white phosphorus is P4. This indicates that there are four phosphorus atoms in the molecule. 2. **Understand the Structure**: - The structure of white phosphorus can be visualized as a tetrahedral arrangement. In this arrangement, each phosphorus atom is bonded to three other phosphorus atoms. 3. **Draw the Tetrahedral Structure**: - When drawing the tetrahedral structure, you can position one phosphorus atom at the center and the other three at the corners of a tetrahedron. This gives a three-dimensional shape. 4. **Determine the Bond Angles**: - In a tetrahedral structure, the bond angles between the atoms are typically 109.5 degrees. However, in the case of white phosphorus, due to the presence of lone pairs and the specific bonding arrangement, the bond angles are actually reduced. 5. **Calculate the Actual Bond Angle**: - The bond angle in white phosphorus (P4) is approximately 60 degrees. This is because the lone pairs of electrons influence the geometry and reduce the bond angles between the phosphorus atoms. 6. **Conclusion**: - Therefore, the shape of white phosphorus is tetrahedral, and the bond angle is approximately 60 degrees. ### Final Answer: - **Shape**: Tetrahedral - **Bond Angle**: 60 degrees
