Document Summary
Jane b. reece, lisa a. urry, michael l. cain, steven a. wasserman, peter v. minorsky, robert b. jackson. 1: vitalism, the idea that organic compounds arise only in organisms, was disproved when chemists synthesized these compounds, mechanism is the view that all natural phenomena are governed by physical and chemical laws. Carbon atoms can form diverse molecules by bonding to four other atoms. Carbon (valence = 2) (valence = 3) (valence = 4) Model (a) methane (b) ethane (c) ethene (ethylene) Carbon atoms can partner with atoms other than hydrogen; for example: Hydrocarbons: hydrocarbons are organic molecules consisting of only carbon and hydrogen. 10 m (a) part of a human adipose cell (b) a fat molecule. Figure 4. 5 (a) length (c) double bond position. Figure 4. 7 (a) structural isomers (b) cis-trans isomers cis isomer: the two xs are on the same side. trans isomer: the two xs are on opposite sides. (c) enantiomers.
