What are the two properties of carbon which lead to the huge number of carbon compounds we see around us?

Carbon compounds:

• The chemical substances that consist of carbon atoms are known as Carbon compounds.
• Generally, Carbon is bonded to other atoms/elements by covalent bonding.
• The basic form of carbon compound is Methane $\left({\mathrm{CH}}_4\right)$.

Properties of Carbon $\left(\mathrm{C}\right)$:

• The valency of carbon is four, thus it can form covalent bonds with other atoms/elements. This property is known as tetravalency.
• Carbon has the ability to form long chains when it gets linked with other carbon atoms. This property is known as Catenation.
• Carbon can form single/double/triple bonds.
