In the outermost shell, the Carbon has four valence electrons. Carbon atom has a tendency to form the four covalent bonds with the help of its four valence electrons.

Because carbon has the tendency to form the four covalent bonds due to the presence of four valence electrons in its outermost shell, the carbon structure can vary its length, branching and ring structure.

Conclusion:

Hence, carbon is the element which is present in the all organic compounds.
