describe how carbon skeletons may vary and explain how this variation contibutes to the diveristy and complecity of organic moleculs

Carbon is a highly covalent element due to the presence of four valence electrons in its outermost shell. This helps it bond covalently with other elements in various ways.

Carbon is known to be the backbone for most compounds. The carbon backbone vary in length and in the mode of bonding such as having the ability to from straight, branched, rings, double or triple bond which contibutes to the diversity and complexity of organic molecules.
