Lewis Dot Structure Exceptions happen when the central element violates the Octet Rule.
Lewis Dot Structures: Exceptions
Group 2A and 3A elements have incomplete octets. Group 5A-8A elements can have expanded octets.
Lewis Dot Structures: Exceptions Example 1
Determine the Lewis Dot Structure for the following compound:SOCl2
Lewis Dot Structures: Exceptions
Radical compounds always have an odd number of total valence electrons.
Lewis Dot Structures: Exceptions Example 2
Draw the Lewis Dot Structure for the radical hydroxide, OH.
Draw the Lewis Dot Structure for POCl3.
