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.
![**Identifying Isomers and Resonance Structures**
### Determine the relationship between Structure A and Structure B in each row of the table.
#### Table:
1. **Row 1:**
- **Structure A:**
- Two carbon atoms (C) double-bonded.
- The left carbon has two hydrogen atoms (H) and a hydroxyl group (OH).
- The right carbon is bonded to one hydrogen and another hydroxyl group.
- **Structure B:**
- Similar to Structure A but the hydroxyl groups are on different carbons.
- **Relationship:**
- **Isomers**
2. **Row 2:**
- **Structure A:**
- Three carbon atoms in a chain.
- The left and right carbons have three hydrogen atoms each, while the middle carbon is double-bonded to an oxygen atom (O).
- **Structure B:**
- Identical to Structure A in terms of bonding and arrangement.
- **Relationship:**
- **Resonance Structures**
3. **Row 3:**
- **Structure A:**
- Three-carbon chain with nitrogen (N) triple-bonded to the first carbon.
- The second carbon is bonded to two hydrogen atoms.
- **Structure B:**
- Similar structure but with a positive charge on the middle carbon and a negative charge on the nitrogen.
- **Relationship:**
- **Resonance Structures**
**Note:**
- **Isomers** are compounds with the same molecular formula but different connectivity or arrangement of atoms.
- **Resonance Structures** are different ways to draw the same molecule, showing the delocalization of electrons.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbc207266-2a46-4653-b180-6d91cc342ad5%2F7f399338-44ad-4589-832d-54d19cdd96ac%2Fbfrmb9k_processed.jpeg&w=3840&q=75)
