Quick Summary

The term "carbon skeleton" refers to the arrangement of carbon atoms in organic compounds, which form the fundamental framework of these molecules. Carbon's unique ability to form extensive networks of covalent bonds with itself allows for an immense diversity of molecular structures, ranging from simple chains to complex rings.12

Carbon atoms typically form four covalent bonds, directed in a tetrahedral arrangement, enabling the creation of compounds with high molecular weights and varied three-dimensional shapes. The possibilities for structural diversity are further expanded by the inclusion of other elements like hydrogen, oxygen, and nitrogen. This structural versatility is crucial, as organic compounds are essential for all known life, forming the basis of foodstuffs, biological molecules, fuels, plastics, and more.12
