Resonance Structures of NO3-

The video tutorial explains resonance in NO3- by first drawing its Lewis structures. It shows that NO3- can have three resonance structures, each with a different placement of the double bond. In reality, NO3- exists as an average of these structures, with bonds that are one and a third in length. The tutorial highlights the limitations of Lewis structures in representing molecules in two dimensions and emphasizes that resonance structures help understand electron distribution, even though only one average structure exists in reality.

What is the first step in analyzing resonance for NO3-?

• Calculating molecular weight

• Measuring bond angles

• Drawing a Lewis structure

• Identifying the number of protons

How many different ways can the double bond be placed in the Lewis structure of NO3-?

• Two ways

• One way

• Three ways

• Four ways

What do the resonance structures of NO3- help us understand?

• The molecular weight

• The boiling point

• The color of the compound

In the real world, how is NO3- represented?

• As a pair of structures

• As an average of three structures

• As a dynamic structure

• As a single structure

What is the nature of the bonds in the real-world representation of NO3-?

• Double bonds only

• Single bonds only

• Triple bonds

• One and a third bonds

Why do we draw resonance structures?

• To predict color
