Beginning Organic Chemistry (BOC)
3. Line Drawings.
Return to BOC Index.
Of the many ways of writing down the structures of simple organic compounds, a line drawing must be the easiest and quickest.
|CH3-CH2-CH3||Three carbons, two at end of lines, one at the junction of the two lines.||CH3-CH2-CH2-CH2-CH3||Similar to above, five carbons|
|Where three lines meet there is just one hydrogen|
|Six carbons in a ring, two hydrogens at each carbon. Note from the model that the ring is not flat!|
|A carbon carbon triple bond shown here. There are no hydrogens on the two carbons of this bond, nor at the carbon bonded to four other carbons.|
|Where three lines meet there is just one hydrogen, the hydrogen on the oxygen is indicated by its symbol.|
There are no formulae or comments with these. Make sure that you can relate the line drawing to the model, especially to the number of carbons and to the number of hydrogens on each carbon.
