They are all homologues that contain a benzene ring
Among the substances listed, pyridine is the most readily soluble in water. This is due to its polar nature and the presence of a nitrogen atom that can form hydrogen bonds with water molecules. In contrast, benzene, octane, carbon tetrachloride, and toluene are largely nonpolar and exhibit low solubility in water.
An aromatic hydrocarbon is represented by a structural formula that includes a benzene ring, characterized by alternating double bonds between carbon atoms, or by a circle within a hexagonal ring of carbon atoms. The simplest example is benzene (C₆H₆), which has the formula represented as a hexagon with a circle inside, indicating resonance among the carbon-carbon bonds. Other aromatic hydrocarbons, like toluene or naphthalene, also contain this benzene ring structure but with additional carbon and hydrogen substituents.
At room temperature, butane has the highest vapor pressure among the three compounds, followed by ethanol and then toluene. This means that butane will evaporate the fastest.
Alcohol will evaporate the fastest among common drinks, due to its lower boiling point compared to water. The rate of evaporation will be influenced by factors such as temperature, surface area, and air flow.

Benzene is classified as an organic compound because it contains carbon atoms bonded together in a cyclic structure. Organic compounds are generally characterized by the presence of carbon and hydrogen atoms, among others. Benzene is an example of an aromatic hydrocarbon and is widely used as a precursor for many organic compounds.
