- 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 [8]
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.
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:
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:
Allotropy
Allotropy: It is a property by which an element can exist in more than one form that is physically different and chemically similar.
Key Points
Key Points: Carbon: A Versatile Element
Key Points: Conventional Sources of Energy > Natural Gas
- Natural gas is a fossil fuel found along with petroleum and mainly consists of methane (about 95%).
- It is used in different forms such as LPG (cooking gas), CNG (vehicle fuel) and PNG (piped gas for homes).
- Mumbai High is the largest producer of natural gas in India; other producing areas include Assam, Gujarat, Andhra Pradesh, Rajasthan, Tripura and Tamil Nadu.
- Natural gas is a cleaner and eco-friendly fuel as it emits less carbon dioxide and leaves no solid residue.
- It is non-renewable, highly inflammable, and requires costly infrastructure for extraction, storage and transport.
