Practice: Determine the Lewis Dot Structure for the following compound: SOCl2
Lewis Dot Structure Exceptions happen when the central element violates the Octet Rule.
Concept #1: Lewis Dot Structures: Exceptions
Group 2A and 3A elements have incomplete octets. Group 5A-8A elements can have expanded octets.
Example #1: Draw the Lewis Dot Structure for xenon dibromide molecule, XeBr2.
Practice: Determine the Lewis Dot Structure for the following compound: SOCl2
Concept #2: Radicals
Radical compounds always have an odd number of total valence electrons.
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–.
