Drawing Lewis Structures For Simple Organic Compounds
To save time chemists usually depict a bond as a line drawn from one atomic symbol to another. Such representations are called Lewis structures rather than Lewis electron dot structures.

Figure 6 shows Lewis structures for each of the molecules presented in Figures 1-4. It is the simplest alkyne hydrocarbon with carbon-carbon triple bonds. Lewis structures or Lewis dot diagrams of compounds is a simple yet effective method of indicating the chemical bonds especially the covalent bonds between the atoms of a compound.
C 2 H 2 is the symbol for the simple organic compound acetylene. This is probably the most difficult step in drawing Lewis structures because we must pick one or multiple atoms to be the central connector to terminal outside atoms. Write the correct skeletal structure for the molecule.
More commonly organic and biological chemists use an abbreviated drawing convention called line structures. Practice drawing Lewis structures for simple molecules. This chemistry image provides a basic introduction into how to draw lewis structures of common molecules such as Cl2 O2 OF2 CH4 NH3 H2O C2H2 and N2H4.
The convention is quite simple and makes it easier to draw molecules but line structures do take a little bit of getting used to. The methods reviewed above for drawing Lewis structures and determining formal charges on atoms are an essential starting point for a novice organic chemist and work quite will when dealing with small simple structures. Drawing each bond in a molecule as two dots gets old very fast.
