Practice: Draw all possible resonance structures for the chlorate ion, ClO3–?
Resonance Structures are used to represent the different possible bonding arrangements of a molecule.
Examining Resonance Structures
Concept #1: Resonance Structures
Resonance Hybrid is made up of all the major resonance structures.
Example #1: Determine the remaining resonance structures possible for the carbonate ion, CO32–
Example #2: Determine the average charge of the oxygen atoms within the phosphate ion.
Average Charge is the charge of an element from overall charges of ALL its resonance structures.
Practice: Determine the average charge of the oxygen atoms within the chlorite ion, ClO2–.
Practice: Determine which of the following drawings would be the best structure for the N2O molecule.
a) a
b) b
c) c
d) All are equally stable
Practice: Which of the following phosphate, PO43- Lewis structures is the best, most valid resonance structure?
Practice: Draw all the resonance structures for the following ionic compound: RbIO2
