B. `106^(@)` and `96^(@)`
C. `107^(@)` and `108^(@)`
D. `96^(@)` and `106^(@)`

Answer

To determine the Cl-S-Cl and Cl-S-O bond angles in SOCl₂, we need to follow these steps:

### Step 1: Draw the Lewis Structure of SOCl₂
- Sulfur (S) is the central atom, bonded to one oxygen (O) with a double bond and two chlorine (Cl) atoms with single bonds.
- The Lewis structure can be represented as:
```
Cl
|
S=O
|
Cl
```

### Step 2: Determine the Molecular Geometry
- The central atom (S) has two single bonds to Cl and one double bond to O.
- This gives a total of three regions of electron density around the sulfur atom.
- According to VSEPR theory, three regions of electron density will adopt a trigonal planar geometry.

### Step 3: Analyze the Bond Angles
- In a perfect trigonal planar geometry, the bond angles would be 120°.
- However, due to the presence of the double bond (S=O), which has a stronger repulsion than single bonds, the bond angles will be slightly altered.

### Step 4: Estimate the Cl-S-Cl and Cl-S-O Bond Angles
- The Cl-S-Cl bond angle (θ₁) will be slightly less than 120° due to the repulsion from the double bond.
- The Cl-S-O bond angle (θ₂) will also be slightly less than 120° but may be affected more by the presence of the double bond, leading to a smaller angle than θ₁.

### Conclusion
- The Cl-S-Cl bond angle (θ₁) is approximately 107°.
- The Cl-S-O bond angle (θ₂) is approximately 108°.

### Final Answer
- Cl-S-Cl bond angle (θ₁) ≈ 107°
- Cl-S-O bond angle (θ₂) ≈ 108°
