1. Carbon can form four bonds which makes it a very sociable atom.

Tetravalent
We have already seen an example of how a covalent bond can form between two hydrogen atoms producing molecular (H2) as opposed to the atomic form of hydrogen. ... As in all its compounds and its elemental forms, carbon is tetravalent, which means that it always forms four bonds.

The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, according for the importance of carbon in living things. carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.

Hope this
