The compounds which contains ionic bonds is

Options

A. `CH_(4)`
B. `CHCl_(3)`
C. `NaCl`
D. `O_(2)`

Answer

To determine which compound contains ionic bonds, we need to analyze each option provided:

### Step 1: Understand Ionic Bonds
Ionic bonds are formed when one atom transfers electrons to another, resulting in the formation of positively and negatively charged ions. The electrostatic attraction between these oppositely charged ions creates the ionic bond.

### Step 2: Analyze Each Compound
1. **CH4 (Methane)**:
- Methane consists of one carbon atom bonded to four hydrogen atoms. The bonds are formed by sharing electrons (covalent bonds).
- **Conclusion**: CH4 does not contain ionic bonds.

2. **CSCl3 (Chloroform)**:
- Chloroform consists of one carbon atom bonded to one hydrogen atom and three chlorine atoms. Similar to methane, these bonds are covalent as they involve sharing of electrons.
- **Conclusion**: CSCl3 does not contain ionic bonds.

3. **NaCl (Sodium Chloride)**:
- Sodium chloride is formed when sodium (Na) donates one electron to chlorine (Cl). Sodium becomes a positively charged ion (Na⁺), and chlorine becomes a negatively charged ion (Cl⁻). The attraction between these ions forms an ionic bond.
- **Conclusion**: NaCl contains ionic bonds.

4. **O2 (Oxygen)**:
- Oxygen consists of two oxygen atoms sharing electrons to fill their outer shells, forming a covalent bond.
- **Conclusion**: O2 does not contain ionic bonds.

### Step 3: Identify the Correct Answer
From the analysis, the only compound that contains ionic bonds is **NaCl (Sodium Chloride)**.

### Final Answer
The compound which contains ionic bonds is **NaCl (Sodium Chloride)**.
