Document Summary
To understand how we interact with: other organisms (food and nutrients, infections, our environment (aromas, pollutants, drugs, ourselves (metabolism, growth, immunity, cancer, to understand how things are made, what they"re made of, what they react with Organic chemistry components: structure: the connectivity and 3d nature of compounds, theory: structure and reactivity in term sof atoms and the electrons that bind them together, synthesis: how to design and make new molecules. Hydrocarbons the simplest organic compounds (cnh2n+2) Saturated (all bonding electrons used to make single bonds) Simplest one: methane ch4 tetrahedral, ax4. Propane (c3h8: condensed structural formula: ch3ch2ch3 (still gives connectivity and structural info but easier to write) Hints: count your carbon atoms, count the substituents on carbon atoms including implied h atoms, never more than four bonds to carbon. Structural diversity (isomers, cycloalkanes; section 26-1, part of 26-3) Skeletal or structural isomers have: the same molecular formula but different connectivity, different physical properties.
