The correct Answer is:
To determine the number of `P-O-P` bridges in the structures of phosphorus pentoxide (P4O10) and phosphorus trioxide (P4O6), we can follow these steps: ### Step 1: Understand the molecular formulas - Phosphorus pentoxide has the formula P4O10. - Phosphorus trioxide has the formula P4O6. ### Step 2: Draw the structures - For phosphorus pentoxide (P4O10): - It consists of 4 phosphorus atoms and 10 oxygen atoms. - The structure can be visualized as a cyclic arrangement where each phosphorus atom is connected to oxygen atoms, forming `P-O-P` bridges. - For phosphorus trioxide (P4O6): - It consists of 4 phosphorus atoms and 6 oxygen atoms. - Similar to P4O10, the structure will also have `P-O-P` bridges. ### Step 3: Count the `P-O-P` bridges in P4O10 - In the structure of phosphorus pentoxide, we can identify the `P-O-P` bridges: - Each phosphorus atom is connected to other phosphorus atoms through oxygen. - By analyzing the structure, we find a total of 6 `P-O-P` bridges. ### Step 4: Count the `P-O-P` bridges in P4O6 - In the structure of phosphorus trioxide, we also identify the `P-O-P` bridges: - Similarly, each phosphorus atom connects through oxygen to form bridges. - By analyzing the structure, we find a total of 6 `P-O-P` bridges. ### Conclusion - The number of `P-O-P` bridges in phosphorus pentoxide (P4O10) is 6. - The number of `P-O-P` bridges in phosphorus trioxide (P4O6) is also 6. Thus, the answer is: **6 and 6 respectively.**
