slide 2: organic molecules

19th century chemists thought that cellular molecules contained a “vital force”, divided chemistry into organic and inorganic, we consider organic chemistry to include the study of organic molecules that contain both carbon and hydrogen atoms

slide 3: carbon

the macromolecules that make up living cells all have carbon as the central element, the diversity of these molecules is based on carbon’s unique chemical properties, inorganic carbon enters the biosphere and food chain through the uptake of co2 by autotrophs during photosynthesis

slide 4: properties of carbon

carbon can form 4 covalent bonds equidistance apart creating a tetrahedral shape, it’s a “4-way intersection” for a molecule, methane ch4 is the simplest molecule carbon can form(4 single bonds to hydrogen)

slide 5: properties of carbon

when carbon forms bonds with itself, each group retains the tetrahedral shape as in ethane; when a double bond forms between 2 carbons, the molecule becomes planar as in ethane; carbon can also form ringed structures, many branching patterns= lots of complexity

slide 6: carbon skeletons

majority of organic molecules have a backbone which can be branched, have double bonds, or take the form of rings; each carbon of the backbone is numbered, so different groups attached to the carbons can be identified
