### Question 13
**Draw all major resonance contributors of the species below:**

1. **Structure 1:**
   - Chemical Formula: C₆H₅CH₃⁻
   - Description: A benzene ring with a methyl group attached (CH₃). The negative charge is on the carbon where the methyl group is attached.

2. **Structure 2:**
   - Chemical Formula: C₆H₅-CH=CH-CH₂⁺
   - Description: A benzene ring with a propyl group attached at the first carbon. The positive charge is on the third carbon of the propyl chain.

3. **Structure 3:**
   - Chemical Formula: C₆H₆N⁺(CH₃)
   - Description: A pyridine ring with a methyl group attached to the nitrogen atom. The positive charge is on the nitrogen atom.

4. **Structure 4:**
   - Chemical Formula: C₆H₅-O⁺
   - Description: A benzene ring with a positively charged oxygen atom attached.

5. **Structure 5:**
   - Chemical Formula: C₆H₇-O
   - Description: A benzene ring with an oxygen atom attached via a single bond. The oxygen has three lone pairs of electrons and a negative charge.

**Diagrams and Graphs Explanation:**

Each structure contains a central aromatic ring (benzene or pyridine) with different substituents that impact the electron distribution of the molecule. The positions of the charges and substituents are crucial in understanding how resonance structures can be drawn to depict the delocalization of electrons within these aromatic systems.

Remember to draw all possible resonance contributors to illustrate how electrons can be delocalized across the molecular framework. This helps in understanding the stability and reactivity of the given species.
