How many `P=O` bond are presents in `H_(3)PO_(5)` ?

Options

A. 1
B. 4
C. 2
D. 5

Answer

To determine how many P=O (phosphorus double bond oxygen) bonds are present in H₃PO₅, we can follow these steps:

### Step 1: Understand the Molecular Structure of H₃PO₅
H₃PO₅ is known as peroxo-monophosphoric acid. It is important to visualize or draw the structure of this molecule to identify the bonds present.

### Step 2: Draw the Structure
The structure of H₃PO₅ includes:
- One phosphorus (P) atom at the center.
- Three hydroxyl (OH) groups attached to the phosphorus.
- One peroxo (OOH) group attached to the phosphorus.
- One double bond to an oxygen atom (P=O).

### Step 3: Identify the P=O Bonds
From the structure:
- There is one P=O bond.
- The other bonds include P-OH and P-OOH, but these do not count as double bonds.

### Step 4: Conclude the Count
After analyzing the structure, we find that there is only **one P=O bond** in H₃PO₅.

### Final Answer
Thus, the number of P=O bonds in H₃PO₅ is **1**.
