Structure of `S_(2)Cl_(2)` is analogous to :

Options

A. `SOCl_(2)`
B. `CO_(2)`
C. `H_(2)S`
D. `H_(2)O_(2)`

Answer

To determine which structure is analogous to \( S_2Cl_2 \), we will analyze the molecular structure of \( S_2Cl_2 \) and compare it with the structures of the given options.

### Step 1: Analyze the Structure of \( S_2Cl_2 \)

1. **Valence Electrons**: Each sulfur (S) atom has 6 valence electrons. Since there are 2 sulfur atoms and 2 chlorine (Cl) atoms, we can calculate the total number of valence electrons:
\[ \text{Total valence electrons} = 2 \times 6 + 2 \times 7 = 12 + 14 = 26 \]

2. **Lewis Structure**: The structure can be drawn as follows:
- Connect the two sulfur atoms with a single bond.
- Connect each sulfur atom to one chlorine atom with single bonds.
- Each sulfur atom will have 2 lone pairs of electrons remaining.

The Lewis structure looks like this:
```
Cl
|
Cl - S - S
|
(Lone pairs)
```

### Step 2: Compare with Given Options

Now, we will analyze the structures of the given options one by one.

#### Option A: \( SOCl_2 \)

1. **Structure**: Sulfur is bonded to one oxygen (double bond) and two chlorine atoms (single bonds). The structure is:
```
Cl
|
Cl - S = O
|
(Lone pair)
```
- **Lone pairs**: 1 on sulfur.
- **Shape**: Not similar to \( S_2Cl_2 \).

#### Option B: \( CO_2 \)

1. **Structure**: Carbon is bonded to two oxygen atoms with double bonds:
```
O = C = O
```
- **Shape**: Linear, not similar to \( S_2Cl_2 \).

#### Option C: \( H_2S \)

1. **Structure**: Sulfur is bonded to two hydrogen atoms:
```
H
|
H - S
(Lone pairs)
```
- **Lone pairs**: 2 on sulfur.
- **Shape**: Bent, but not analogous to \( S_2Cl_2 \).

#### Option D: \( H_2O_2 \)

1. **Structure**: The structure of hydrogen peroxide is:
```
H H
| |
O - O
(Lone pairs)
```
- **Lone pairs**: 2 on each oxygen.
- **Shape**: Similar to \( S_2Cl_2 \) as both have a central atom with two single bonds and two lone pairs.

### Conclusion

After analyzing all options, the structure of \( H_2O_2 \) (Option D) is the most analogous to \( S_2Cl_2 \).

**Final Answer**: The structure of \( S_2Cl_2 \) is analogous to **Option D: \( H_2O_2 \)**.
