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

Options

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

Answer

To solve the question regarding the number of covalent bonds formed by the central atom in the compounds CO₂, SO₂, and SiO₂, we will analyze each compound step by step.

### Step 1: Analyze CO₂ (Carbon Dioxide)
- The central atom in CO₂ is carbon (C).
- Carbon forms double bonds with two oxygen (O) atoms.
- Therefore, in CO₂, the number of covalent bonds formed by the central atom (C) is **2**.

### Step 2: Analyze SO₂ (Sulfur Dioxide)
- The central atom in SO₂ is sulfur (S).
- Sulfur forms double bonds with two oxygen (O) atoms.
- Thus, in SO₂, the number of covalent bonds formed by the central atom (S) is also **2**.

### Step 3: Analyze SiO₂ (Silicon Dioxide)
- The central atom in SiO₂ is silicon (Si).
- Silicon forms single bonds with four oxygen (O) atoms in the tetrahedral structure of SiO₂.
- Therefore, in SiO₂, the number of covalent bonds formed by the central atom (Si) is **4**.

### Conclusion
- In summary:
- CO₂: 2 covalent bonds (C with 2 O)
- SO₂: 2 covalent bonds (S with 2 O)
- SiO₂: 4 covalent bonds (Si with 4 O)

Thus, the central atoms in CO₂, SO₂, and SiO₂ are covalently bonded with 2, 2, and 4 oxygen atoms respectively.

### Final Answer
- The correct answer is that the central atoms in CO₂ and SO₂ are bonded with **2** oxygen atoms each, while the central atom in SiO₂ is bonded with **4** oxygen atoms.
