The correct Answer is:
To determine the total number of P=O (double bonds) and P-O (single bonds) in cyclotrimetaphosphoric acid (H3O9P3), we can follow these steps: ### Step 1: Understand the Molecular Formula The molecular formula of cyclotrimetaphosphoric acid is H3O9P3. This indicates that there are three phosphorus (P) atoms in the structure. **Hint:** Familiarize yourself with the molecular formula to identify the number of phosphorus atoms. ### Step 2: Draw the Structure To analyze the bonds, we need to draw the structure of cyclotrimetaphosphoric acid. The structure consists of a cyclic arrangement of phosphorus and oxygen atoms. **Hint:** Visualize the cyclic structure, which helps in identifying the types of bonds present. ### Step 3: Identify P=O Bonds In the structure, identify the phosphorus atoms that are double-bonded to oxygen. Each double bond is represented as P=O. - Count the P=O bonds: - There are 3 P=O bonds in the structure. **Hint:** Look for the double bonds between phosphorus and oxygen in the structure. ### Step 4: Identify P-O Bonds Next, identify the P-O single bonds. These are the bonds where phosphorus is connected to oxygen with a single bond. - Count the P-O bonds: - There are 9 P-O single bonds in the structure. **Hint:** Count all the single bonds connecting phosphorus to oxygen. ### Step 5: Summarize the Findings Based on the counts from the previous steps, we conclude that cyclotrimetaphosphoric acid has: - 3 P=O (double bonds) - 9 P-O (single bonds) ### Final Answer Thus, the total number of P=O and P-O bonds in cyclotrimetaphosphoric acid is 3 and 9, respectively. ---
