Lewis Dot Structure Exceptions

Concept #1: Lewis Dot Structures: Exceptions

Example #1: Draw the Lewis Dot Structure for xenon dibromide molecule, XeBr2.

Practice: Determine the Lewis Dot Structure for the following compound: SOCl2

Example #2: Draw the Lewis Dot Structure for the radical of nitrogen dioxide, NO2.

Practice: Draw the Lewis Dot Structure for the radical hydroxide, OH.

Practice: Draw the Lewis Dot Structure for POCl3.

Practice: Metalloids can sometimes adopt the bonding preferences of similar nonmetals. Based on your knowledge of expanded octets, draw the Lewis Dot Structure for the following ion, SiF62–.
