Chapter Four: Carbon and the Molecular Diversity of Life Definitions 1) Organic chemistry: is the branch of chemistry that specializes in the study of carbon compounds. 2) Vitalism: is the belief in a life force outside the jurisdiction of physical and chemical laws. 3) Mechanism: is the view that physical and chemical laws govern all natural phenomena. 4) Hydrocarbons: are organic molecules consisting of only carbon and hydrogen. 5) Isomers: are compounds that have the same numbers of atoms of the same elements but different structures and hence different properties. Notes - Vitalism provided the foundation for the new discipline of organic chemistry. - The tetravalence is one component of carbon’s versatility that makes large complex molecules possible. - When two carbon atoms are joined by a double bond, all atoms attached to those carbons are in the same plane; the molecule is flat. - Methyl group acts as a tag on biological molecules. - Types of isomers:
