This chemistry video tutorial discusses the exceptions to the octet rule while providing the lewis dot diagrams of the molecular compounds involved. BH3 has an incomplete octet - that is, it has less than 8 electrons. Molecules such as ICl5 and PCl5 have an expanded octet which means the center atom has more than 8 electrons. The last category are molecules with odd number of electrons such as NO and NO2. These will always be electron deficient and contain an incomplete octet at the nitrogen atom.
