Document Summary
Chapter 4: carbon and the molecular diversity of life. Organic chemistry is the study of carbon compounds: organic chemistry- compounds containing carbon are said to be organic; the study of these compounds is organic chemistry. We have learned to synthesize organic compounds in the lab. Friedrich wohler- german chemist; tried to make inorganic salt- ammonium cyanate. Organic molecules and the origin of life on earth. Stanley miller- helped bring the abiotic (nonliving) synthesis of organic compounds into the context of evolution. Concluded that complex organic molecules could arise spontaneously under conditions thought at that time to have existed on early earth. Major elements of life- c, h, o, n, s, and p. Carbon atoms can form diverse molecules by bonding to four other atoms: key to an atom"s chemical characteristics is its electron configuration. The configuration determines what kinds and number of bonds an atom will form with other atoms. The formation of bonds with carbon: carbon has 6 electrons.
