Chemistry
  • A volatile liquid hydrocarbon of the alkane series, present in petroleum-based solvents.

    • ‘After thawing, the volatile components were extracted three times with 50 ml pentane.’
    • ‘The pentane molecule, however, has neither hydrogen bonding nor polar groups to be attracted to water molecules.’
