Question

give reason for the fact that the bonds formed by carbon forms a very large compounds. why?

Answer 1

the reasons are-
1 catenation
2 tetravalency of carbon atoms.

Answer 2

Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation. No other element exhibits the property of catenation to the extent seen in carbon compounds.

Carbon has a valency of four, it is capable of bonding with four other atoms of carbon or atoms of some other mono-valent element.
