HOMEWORK: The Octet Rule and Its Exceptions

While Lewis electron dot structures help determine bonding in most compounds, there are three general exceptions:

  1.  molecules in which atoms have fewer than 8 electrons (e.g., boron chloride and lighter s- and p- block elements)
  2.  molecules in which atoms have more than 8 electrons (.e.g, sulfur hexafluoride and elements beyond period 3)
  3.  molecules with an odd number of electrons (e.g., NO).

In your notebooks explain/expand each of the aforementioned exceptions to the octet rule and provide an example for each.

DUE DATE:  Friday 24th

 ( just leave your notebooks on my desk when you come in before or after flag ceremony)
