- Carbon forms many compounds, from simple ones like methane to complex ones like DNA, due to its bonding versatility.
- Catenation allows carbon to form long chains or rings by bonding with itself.
- Carbon forms single, double, and triple covalent bonds, leading to saturated and unsaturated compounds.
- Being tetravalent, carbon forms four strong covalent bonds with elements like H, O, N, and Cl.
- Isomerism increases the number of carbon compounds by allowing different structures with the same molecular formula.
Definitions [14]
Definition: Catenation
The property of self-linking of atoms of an element through covalent bonds in order to form straight chains, branched chains and cyclic chains of different sizes is known as catenation.
Define the following:
Adsorption
Adsorption is the property due to which a substance absorbs gases, liquids and solids on its surface.
Define the following:
Carbonization
The process of the slow conversion of vegetable matter into carbon-rich substances is called carbonization.
Define catenation.
Carbon possesses a unique property of combining with other carbon atoms to form long chains. This property is called catenation. The chains can be straight, branched or closed.
The self-linking property of atoms of an element to form very long straight or branched chains and cyclic rings is known as catenation. This property is shown by carbon whose small size and tetravalency helps it to form large structures by self-linking.
Definition: Tetravalency of Carbon
The characteristic of the carbon atom, by virtue of which it forms four covalent bonds, is called the tetravalency of carbon.
Define:
Allotropy
Allotropy: It is a property by which an element can exist in more than one form that is physically different and chemically similar.
Define:
Allotrope
Allotrope: The different forms of an element.
Define the term catenation.
Carbon has the unique property of combining any number of carbon atoms to form straight chains, branched chains and rings of different sizes. This property is called catenation.
Define Allotrophy
When an element possess 2 or more different forms in the same state, they are called allotropes and the phenomenon is known as allotropy. Diamond and graphite are the 2 allotropes of carbon.

Definition: Aromatic Compounds
The compounds having this characteristic unit in their structure are called aromatic compounds.

The compounds having this characteristic unit in their structure are called aromatic compounds.
Definition: Organic Compounds
All the compounds having carbon as a constituent element are called as organic compounds.
Definition: Covalent Bond
The chemical bond formed by sharing of two valence electrons between the two atoms is called covalent bond.
Key Points

Key Points: Bonds in Carbon Compounds
- Organic compounds are mainly carbon compounds, except CO₂, CO, carbonates, bicarbonates, and carbides, which are inorganic.
- Carbon compounds have low melting and boiling points (generally below 300 °C) due to weak intermolecular forces.
- Most carbon compounds do not conduct electricity, showing the absence of ionic bonds.
- Carbon forms covalent bonds by sharing electrons to achieve a stable noble gas configuration.
- Carbon can form single, double, and triple covalent bonds, allowing the formation of many compounds like CH₄, O₂, and N₂.
