Hi, I need some assistance answering the following questions:
1. Use the concept of resonance to explain why all six C-C bonds in benzene are equal in length.
2. Do you expect the O-O bond in H2O2 to be longer or shorter than the O-O bond in O2?
3. Consider the nitryl cation, NO2+
- Are resonance structures needed to describe the structure?
- With what familiar molecule is it isoelectronic? Why?
4. View attachment to see this question.

1. Use the concept of resonance to explain why all six bonds in benzene are equal in length.

Resonance for benzene is as shown below.

Consider the C1-C2 bond. In one structure it is shown as a single bond and in the other a double bond. Every carbon-carbon bond is found to be a mix of one single and one double bond. So each bond is 1.5 bond order. Hence all bonds are equal in length. ...
