The number of S-S bonds, in sulpher trioxide trimer `(S_(3)O_(9))` is :

Options

A. three
B. two
C. one
D. zero

Explanation

To determine the number of S-S bonds in sulfur trioxide trimer (S₃O₉), we can follow these steps:

### Step 1: Understand the Structure of Sulfur Trioxide (SO₃)
Sulfur trioxide (SO₃) consists of one sulfur atom bonded to three oxygen atoms. Each sulfur atom forms double bonds with the oxygen atoms.

### Step 2: Analyze the Trimer (S₃O₉)
In the trimer S₃O₉, there are three sulfur atoms and a total of nine oxygen atoms. The structure can be visualized as three sulfur atoms connected by oxygen atoms.

### Step 3: Draw the Structure
When we draw the structure of S₃O₉, we place the three sulfur atoms in a triangular arrangement with oxygen atoms bridging them. Each sulfur atom forms double bonds with two oxygen atoms.

### Step 4: Identify S-S Bonds
In the drawn structure, we observe that:
- Each sulfur atom is only bonded to oxygen atoms.
- There are no direct bonds between the sulfur atoms themselves.

### Step 5: Conclusion
Since there are no S-S bonds present in the structure of sulfur trioxide trimer (S₃O₉), the number of S-S bonds is **zero**.

### Final Answer
The number of S-S bonds in sulfur trioxide trimer (S₃O₉) is **0**.
