As we noted earlier, a covalent bond is drawn as a dash in a Lewis structure. Also, in a Lewis structure, nonbonding electron pairs are shown as “dots.” The Lewis structures of four simple organic compounds: methane, aminomethane, methanol, and chloromethane are shown below with both bon...
Construct a Lewis electron-dot structure that describes the bonding in a simple molecule or ion, including an example that contains lone pair electrons. Define bond order, and draw electron-dot structures for molecules with double and triple bonds. Explain the meaning of a "resonance hybrid";...

Lewis created an illustration called the “Lewis dot structure” which portrayed covalent bonds. …show more content… By sharing these valence electrons, it creates a full electron shell. o Demonstration: H2O, the water molecule is the perfect example of how covalent bonding uses valence ...
