Linear Molecule : Two bonding locations and No Lone Pairs



This is an example of a linear molecule that contains no lone pairs. This is the carbon dioxide molecule, CO2, which has 16 valence electrons to use for the lewis dot structure. When the lewis dot structure is drawn there are two bonding locations and no lone pairs on the central atom. This type of configuration would give you a linear molecular geometry. This geometry has only one angle between the atoms which is 180 degrees. Try it with these two other linear molecules: Hydrogen cyanide (HCN) and ethyne (C2H2).

that example (HCN) almost stumped me... i should have left you a comment about that... next time...
