What are the two properties of carbon which lead to the huge number of carbon compounds we see around us?
What are the two properties of carbon which lead to the formation of a large number of carbon compounds?
उत्तर
The two features of carbon that give rise to a large number of compounds are as follows:
- Catenation: Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation.
- Linking of carbon with other atoms: Carbon is tetravalent, meaning it can quickly form bonds with atoms such as hydrogen, oxygen, nitrogen, and sulfur through electron sharing.
