Minimum `F-S-F` bond angle present in :

Options

A. `SSF_(2)`
B. `SF_(6)`
C. `SF_(2)`
D. `F_(3)SSF`

Explanation

To determine the minimum `F-S-F` bond angle present in the given compounds, we will analyze the molecular geometry of each compound step by step.

### Step 1: Analyze SF2 (Sulfur Difluoride)
- **Structure**: SF2 has a bent shape due to the presence of lone pairs on the sulfur atom.
- **Lone Pairs**: Sulfur has 2 lone pairs and forms 2 bonds with fluorine.
- **Bond Angle**: The ideal bond angle in a tetrahedral arrangement is 109.5 degrees, but the presence of lone pairs reduces the bond angle. The actual bond angle in SF2 is approximately 98 degrees.

### Step 2: Analyze SF6 (Sulfur Hexafluoride)
- **Structure**: SF6 has an octahedral geometry.
- **Bond Angle**: In an octahedral structure, the bond angles between adjacent fluorine atoms are 90 degrees. Therefore, the bond angle in SF6 is 90 degrees.

### Step 3: Analyze F3SSF (Trifluorodisulfur Difluoride)
- **Structure**: F3SSF has a structure where both sulfur atoms have lone pairs.
- **Lone Pairs**: Each sulfur atom has 1 lone pair, which affects the bond angles.
- **Bond Angle**: The presence of lone pairs will reduce the bond angle from the ideal angle. The bond angle in F3SSF is less than 90 degrees.

### Step 4: Analyze S2F2 (Disulfur Difluoride)
- **Structure**: S2F2 can also be represented as having a bent shape due to lone pairs on sulfur.
- **Lone Pairs**: Each sulfur atom has lone pairs, which will affect the bond angles.
- **Bond Angle**: Similar to SF2, the bond angle will be less than 109.5 degrees due to the lone pairs.

### Conclusion
After analyzing all the compounds:
- SF2 has a bond angle of approximately 98 degrees.
- SF6 has a bond angle of 90 degrees.
- F3SSF has a bond angle less than 90 degrees.
- S2F2 has a bond angle less than 109.5 degrees.

The minimum `F-S-F` bond angle is found in **F3SSF**, which is less than 90 degrees.

### Final Answer
The minimum `F-S-F` bond angle is present in **F3SSF** (Trifluorodisulfur Difluoride) and is less than 90 degrees.
