What and Why is more volatile benzene or acetone?

Benzene is generally more volatile than acetone due to its lower boiling point and higher vapor pressure at room temperature. Benzene has a boiling point of about 80.1°C, while acetone's is around 56.5°C; however, the volatility is also influenced by molecular structure and intermolecular forces. Benzene's non-polar structure leads to weaker van der Waals forces compared to the polar nature of acetone, resulting in higher volatility for benzene. Therefore, benzene evaporates more readily under similar conditions.
