# The complete Lewis structures of benzene, \(\text{C}_6\text{H}_6\), and cyclohexa-1,3-diene, \(\text{C}_6\text{H}_8\), are represented below.

What is the ratio of the number of \(\sigma\) bonds to \(\pi\) bonds in a molecule of benzene and in a molecule of cyclohexa-1,3-diene?

The complete Lewis structures of benzene, \(\text{C}_6\text{H}_6\), and cyclohexa-1,3-diene, \(\text{C}_6\text{H}_8\), are represented below.

What is the ratio of the number of \(\sigma\) bonds to \(\pi\) bonds in a molecule of benzene and in a molecule of cyclohexa-1,3-diene?

![Two complete structural Lewis diagrams drawn side by side in black line art on a white background. On the left, a regular hexagonal ring of six \(\text{C}\) atoms representing benzene: three alternating single \(\text{C}-\text{C}\) bonds and three double \(\text{C}=\text{C}\) bonds form the ring. Each \(\text{C}\) atom is bonded to exactly one \(\text{H}\) atom via a single outward-pointing line, showing six \(\text{C}-\text{H}\) single bonds in total. Labeled 'Benzene' below the structure. On the right, a hexagonal ring of six \(\text{C}\) atoms representing cyclohexa-1,3-diene: two conjugated double \(\text{C}=\text{C}\) bonds and four single \(\text{C}-\text{C}\) bonds form the ring. Four \(\text{C}\) atoms each have one outward single bond to an \(\text{H}\) atom, and two adjacent \(\text{C}\) atoms each have two outward single bonds to two separate \(\text{H}\) atoms, showing eight \(\text{C}-\text{H}\) single bonds in total. Labeled 'Cyclohexa-1,3-diene' below the structure. No lone pairs, charges, or other annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596813-Fnwe1q.jpg)

- **A.** Benzene: \(2 : 1\); Cyclohexa-1,3-diene: \(3 : 1\)
