In `CO_(2),SO_(2),SiO_(2)` each central atom is covalently bonded with :-

Options

A. 2,2,4 oxygen atom respectively
B. 2,2,2 oxygen atom respectively
C. 2,4,4 oxygen atom respectively
D. 4,4,4 oxygen atom respectively

Answer

To solve the question regarding how many oxygen atoms are covalently bonded with each central atom in CO₂, SO₂, and SiO₂, we will analyze each compound step by step.

### Step 1: Analyze CO₂ (Carbon Dioxide)
- The molecular structure of CO₂ consists of one carbon atom (C) in the center and two oxygen atoms (O) on either side.
- Each oxygen atom is double-bonded to the carbon atom.
- Therefore, the number of oxygen atoms covalently bonded to the central carbon atom is **2**.

### Step 2: Analyze SO₂ (Sulfur Dioxide)
- The molecular structure of SO₂ consists of one sulfur atom (S) in the center and two oxygen atoms (O) bonded to it.
- The sulfur atom forms a double bond with one oxygen atom and a single bond with the other oxygen atom, resulting in a bent molecular shape due to the presence of a lone pair on sulfur.
- Thus, the number of oxygen atoms covalently bonded to the central sulfur atom is **2**.

### Step 3: Analyze SiO₂ (Silicon Dioxide)
- The structure of SiO₂ is more complex. Each silicon atom (Si) is tetrahedrally coordinated with four oxygen atoms (O).
- In the extended structure of SiO₂, each silicon atom is bonded to four oxygen atoms in a three-dimensional network.
- Therefore, the number of oxygen atoms covalently bonded to the central silicon atom is **4**.

### Summary of Results
- For CO₂: 2 oxygen atoms
- For SO₂: 2 oxygen atoms
- For SiO₂: 4 oxygen atoms

### Final Answer
The central atoms in CO₂, SO₂, and SiO₂ are covalently bonded with:
- CO₂: 2
- SO₂: 2
- SiO₂: 4
