The more carbon atoms there are in an alkane, the greater the surface area available for intermolecular interactions. Van der Waals intermolecular forces increase as chain length increases. Image by Duncan Watson. Hydrocarbons are generally of low toxicity, hence the widespread use of gasoline and related volatile products. Aromatic compounds such as benzene and toluene are narcotic and chronic toxins, and benzene in particular is known to be carcinogenic. Certain rare polycyclic aromatic compounds are carcinogenic.
