In each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. If the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge. O The highlighted bond is polar and :Cl – F: the more negative atom isU The highlighted bond is nonpolar. The highlighted bond is polar and :NEN: the more negative atom isU The highlighted bond is nonpolar. H The highlighted bond is polar and the more negative atom isO :0 — Н The highlighted bond is nonpolar.
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.

1. **Cl—F:**
- Options:
- The highlighted bond is polar and the more negative atom is [ ]
- The highlighted bond is nonpolar.
2. **N≡N:**
- Options:
- The highlighted bond is polar and the more negative atom is [ ]
- The highlighted bond is nonpolar.
3. **H—O—H:**
- Options:
- The highlighted bond is polar and the more negative atom is [ ]
- The highlighted bond is nonpolar.
### Explanation:
- **Cl—F Molecule:** The bond between chlorine and fluorine is shown in red. Determine the bond polarity and identify the more electronegative atom if polar.
- **N≡N Molecule:** The triple bond between nitrogen atoms is highlighted. Analyze for polarity.
- **H—O—H Molecule:** The bond between oxygen and one hydrogen is highlighted. Consider polarity and identify the more electronegative atom.
