Among the bonds formed by a chlorine atom with atoms of hydrogen, chlorine, sodium and carbon, the strongest bond is formed between

Options

A. `H - Cl`
B. `Cl - Cl`
C. `Na - Cl`
D. ` C - Cl`

Explanation

To determine which bond formed by a chlorine atom with hydrogen, chlorine, sodium, and carbon is the strongest, we need to analyze the nature of each bond based on electronegativity differences and bond types.

### Step-by-Step Solution:

1. **Identify the Atoms Involved**: The atoms we are considering are hydrogen (H), chlorine (Cl), sodium (Na), and carbon (C).

2. **Analyze the Bonds**:
- **H-Cl Bond**: Chlorine has a higher electronegativity than hydrogen. The electronegativity difference is moderate, leading to a polar covalent bond.
- **Cl-Cl Bond**: This bond is between two chlorine atoms, which have the same electronegativity. Therefore, it is a nonpolar covalent bond and does not have a significant bond strength.
- **Na-Cl Bond**: Sodium is a highly electropositive element, while chlorine is highly electronegative. The electronegativity difference is large, resulting in an ionic bond. Ionic bonds are generally stronger than covalent bonds due to the electrostatic attraction between the oppositely charged ions.
- **C-Cl Bond**: Carbon and chlorine have a moderate electronegativity difference, resulting in a polar covalent bond, but it is not as strong as an ionic bond.

3. **Compare the Bond Strengths**:
- The H-Cl bond is a polar covalent bond.
- The Cl-Cl bond is a nonpolar covalent bond.
- The Na-Cl bond is an ionic bond, which is typically the strongest type of bond.
- The C-Cl bond is a polar covalent bond, but weaker than the ionic bond.

4. **Conclusion**: Among the bonds formed by chlorine with hydrogen, chlorine, sodium, and carbon, the strongest bond is the Na-Cl bond due to its ionic nature.

### Final Answer:
The strongest bond is formed between sodium (Na) and chlorine (Cl), resulting in sodium chloride (NaCl).
