Number of S-S bond in `H_(2)S_(n)O_(6)` is :

Options

A. n
B. (n-1)
C. (n-2)
D. (n+1)

Answer

To determine the number of S-S bonds in the compound \( H_2S_nO_6 \), we can follow these steps:

### Step 1: Identify the Structure of the Compound
The first step is to understand the structure of \( H_2S_nO_6 \). This compound consists of sulfur (S), hydrogen (H), and oxygen (O) atoms. The general structure can be visualized as a chain of sulfur atoms connected to each other and to oxygen atoms.

### Step 2: Draw the Basic Structure
We can start by drawing the basic structure of the compound. The central sulfur atoms will be connected to oxygen atoms through double bonds, and there will be hydroxyl (OH) groups attached as well. The structure can be represented as follows:

- The first sulfur atom (S) is connected to two oxygen atoms with double bonds and one hydroxyl group (OH).
- The next sulfur atom is connected to the previous sulfur atom and continues this pattern.

### Step 3: Count the Sulfur Atoms
In the compound \( H_2S_nO_6 \), the number of sulfur atoms is represented by \( n \). Therefore, there are \( n \) sulfur atoms in total.

### Step 4: Determine the Number of S-S Bonds
To find the number of S-S bonds, we need to consider how the sulfur atoms are connected. Each pair of adjacent sulfur atoms forms one S-S bond.

If there are \( n \) sulfur atoms, the number of S-S bonds can be calculated as follows:
- The first sulfur atom connects to the second, the second to the third, and so on, until the \( n^{th} \) sulfur atom.
- Thus, the total number of S-S bonds is \( n - 1 \) (since the last sulfur atom does not connect to another sulfur atom).

### Conclusion
Therefore, the number of S-S bonds in \( H_2S_nO_6 \) is \( n - 1 \).

### Final Answer
The number of S-S bonds in \( H_2S_nO_6 \) is \( n - 1 \).
