Answer 1

Catenation is the self-linking property of carbon i.e carbon atoms form bonds with another carbon atom while tetravalency is the property of carbon atom to combine with another atom of another element i.e carbon atoms form  bonds with atoms of other elements.

I hope you understand  

Answer 2

Answer: (a) Catenation: Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation. (b) Tetravalency: Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element.
