Final answer:
Toluene is more volatile than benzene due to its lower boiling point and the presence of a methyl group.
Step-by-step explanation:
Toluene is more volatile than benzene. Volatility refers to the tendency of a substance to vaporize. Toluene has a lower boiling point than benzene, which means it vaporizes more easily. This is due to the presence of the methyl (CH3) group in toluene, which makes it less stable than benzene.
The structural formula for toluene is C6H5-CH3, with the methyl group attached to the benzene ring. In comparison, benzene has no substituent groups attached to the ring.
For example, toluene has a boiling point of 110.6 °C, while benzene has a boiling point of 80.1 °C. This means that toluene vaporizes more easily at room temperature compared to benzene.
