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

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
The formula \( H_2S_nO_6 \) suggests that we have a compound containing sulfur (S), hydrogen (H), and oxygen (O). The variable \( n \) indicates the number of sulfur atoms in the compound.

### Step 2: Understand the Polythionic Acid
The compound \( H_2S_nO_6 \) is a type of polythionic acid. Polythionic acids are characterized by the presence of multiple sulfur atoms linked together, often resulting in S-S bonds.

### Step 3: Determine the Number of S-S Bonds
In polythionic acids, the general formula for the number of S-S bonds can be derived from the number of sulfur atoms (n). The formula for the number of S-S bonds in \( H_2S_nO_6 \) is given by:
\[ \text{Number of S-S bonds} = n - 1 \]
This means that for every additional sulfur atom, there is one additional S-S bond formed.

### Step 4: Calculate for Specific Values of n
For example:
- If \( n = 2 \) (as in \( H_2S_2O_6 \)), the number of S-S bonds would be:
\[ 2 - 1 = 1 \]
- If \( n = 3 \) (as in \( H_2S_3O_6 \)), the number of S-S bonds would be:
\[ 3 - 1 = 2 \]

### Conclusion
Thus, for the compound \( H_2S_nO_6 \), the number of S-S bonds is \( n - 1 \).
