The number of peroxide linkages in perchloric acid is

Options

A. Zero
B. One
C. Two
D. Four

Answer

To determine the number of peroxide linkages in perchloric acid (HClO4), we can follow these steps:

### Step 1: Understand Peroxide Linkages
Peroxide linkages refer to the presence of an oxygen-oxygen bond (O-O) in a compound. In order to identify the number of peroxide linkages, we need to analyze the structure of the compound in question.

**Hint:** Recall that a peroxide linkage is specifically characterized by an O-O bond.

### Step 2: Analyze the Structure of Perchloric Acid
The molecular formula for perchloric acid is HClO4. To analyze its structure, we can draw the Lewis structure or visualize the arrangement of atoms.

- Perchloric acid consists of one hydrogen atom (H), one chlorine atom (Cl), and four oxygen atoms (O).
- The structure can be represented as follows:
- One oxygen atom is bonded to the hydrogen atom (forming an -OH group).
- The chlorine atom is centrally bonded to the remaining three oxygen atoms through double bonds.

**Hint:** Visualize the arrangement of atoms to see how they are bonded together.

### Step 3: Count the Oxygen-Oxygen Bonds
In the structure of HClO4:
- The oxygen atoms are bonded to the chlorine atom and to the hydrogen atom.
- There are no direct bonds between any two oxygen atoms.

**Hint:** Look specifically for any O-O bonds in the structure you have visualized.

### Step 4: Conclusion
Since there are no oxygen-oxygen bonds present in the structure of perchloric acid, we conclude that the number of peroxide linkages in perchloric acid is zero.

**Final Answer:** The number of peroxide linkages in perchloric acid (HClO4) is **0**.
