Chapter 4 Carbon and the Molecular Diversity of Life The Importance of Carbon 1. Carbon’s electron configuration accounts for its ability to form larger complex and diverse organic molecules because it can form four other bonds with elements. Proteins, DNA, carbohydrates, and other molecules that distinguish living matter from inanimate material are all composed of carbon atoms bonded to one another and to atoms of other elements. 2. Carbon skeletons may vary in length, with some straight, branched, or arranged in close rings. These variations are an important source of complexity and diversity. 3. Hydrocarbons consist of only carbon and hydrogen. They are hydrophobic because the majority of the bonds are nonpolar carbon-to-hydrogen linkages. 4. Isomers are compounds that have the same numbers of atoms of the same element but different structures and different properties. - Structural: differ in covalent arrangement of items - Geometric: same covalent partnerships but differ in spatial arrangements
