Which of the following statement(s) is/are not correct for following compounds?
`(I)SCl_(2)(OCH_(3))_(2) and (II) SF_(2)(OCH_(3))_(2)`

Options

A. `-OCH_(3)` groups in both cases occupy the same position
B. Cl-atoms occupy equitorial position incase of (I) and F-atoms occupy equitorial position in case of (II)
C. Cl-atoms occupy axial position in case of (II) & F-atoms occupy equitorial position in case of (II)
D. Cl and F- atoms occupy either axial or equitorial position in case of (I) and (II) respectively

Explanation

To determine which statements are not correct for the compounds \( \text{SCl}_2(\text{OCH}_3)_2 \) and \( \text{SF}_2(\text{OCH}_3)_2 \), we will analyze the molecular structures and the positions of the substituents.

### Step-by-Step Solution:

1. **Identify the Central Atom and Calculate Steric Number**:
- For both compounds, the central atom is sulfur (S).
- To find the steric number, count the number of bonded atoms and lone pairs around the central atom.
- For \( \text{SCl}_2(\text{OCH}_3)_2 \):
- 2 Cl atoms + 2 OCH3 groups + 1 lone pair = 5 (Steric Number)
- For \( \text{SF}_2(\text{OCH}_3)_2 \):
- 2 F atoms + 2 OCH3 groups + 1 lone pair = 5 (Steric Number)

2. **Determine Hybridization**:
- With a steric number of 5, the hybridization is \( sp^3d \).

3. **Predict Molecular Geometry**:
- The molecular geometry for \( sp^3d \) hybridization is seesaw.

4. **Draw the Structures**:
- **For \( \text{SCl}_2(\text{OCH}_3)_2 \)**:
- The more electronegative \( \text{OCH}_3 \) groups will occupy the axial positions, while the Cl atoms will occupy the equatorial positions.
- **For \( \text{SF}_2(\text{OCH}_3)_2 \)**:
- The more electronegative F atoms will occupy the axial positions, while the OCH3 groups will occupy the equatorial positions.

5. **Analyze the Statements**:
- **Statement A**: "OCH3 groups in both cases occupy the same position."
- **Analysis**: Incorrect. In \( \text{SCl}_2(\text{OCH}_3)_2 \), OCH3 occupies axial, while in \( \text{SF}_2(\text{OCH}_3)_2 \), it occupies equatorial.
- **Statement B**: "Cl atoms occupy equatorial position in case of first and F atoms occupy equatorial position in the case of second."
- **Analysis**: Incorrect. Cl occupies equatorial in the first, but F occupies axial in the second.
- **Statement C**: "Cl atoms occupy axial position in case of 1."
- **Analysis**: Incorrect. Cl occupies equatorial position in \( \text{SCl}_2(\text{OCH}_3)_2 \).
- **Statement D**: "Cl and F atoms occupy either axial or equatorial position in case of one and two respectively."
- **Analysis**: Correct. Cl occupies equatorial in the first, and F occupies axial in the second.

### Conclusion:
The statements that are not correct are A, B, and C.
