Question

why does carbon form compounds mainly by covalent bonding

Answer 1

$\huge\bf\pink{Answer}$

A covalent bond is formed when an atom shares a pair of electron with another atom. Reason: Carbon has 4 electrons in its outer shell and in order to complete its octate, it has to take 4 electrons or donate whereas it shares its 4 electrons with another atom with the same conditions and make 4 covalent bonds. This property of carbon is the only reason behind its ability of formation of long chains. In fact a carbon atom can join with more than one carbon atom to form double, triple covalent bonds. Similarly, it can form bonds with other elements as well due to the presence 4 free electrons in its outer shell.
