Part of speech: noun

Pronunciation: /ˈhɛkseɪn/

Definitions

1. A colorless liquid hydrocarbon consisting of six carbon atoms and fourteen hydrogen atoms, commonly used as a solvent in industrial and laboratory applications
2. A clear, volatile liquid compound made of six carbon atoms and fourteen hydrogen atoms, primarily utilized as a nonpolar solvent in various chemical processes and extractions
3. This substance is a six-carbon alkane that appears as a colorless liquid and is mainly employed in laboratories and industry for dissolving other substances

Etymology: Hexane is a plain piece of chemical naming, built the way organic chemistry names its hydrocarbons. The first part comes from Greek "héx", meaning six, which passed through the combining form "hexa-" into English as "hex-". The ending "-ane" is the suffix chemists use for saturated hydrocarbons, and it descends from the Latin "-ānus" through the same family of forms that gave English "-ane" in names like methane and propane. Put together, the name simply tells you the molecule has six carbon atoms. The pattern is systematic. Chemists count carbon atoms with Greek numerals and attach the matching stem to "-ane", so the series runs from methane (one carbon) and ethane (two) up through propane and butane, with hexane following the same logic. The Greek root in "hex-" also appears in words like hexagon, which likewise describes six sides or angles, so the two words share a root even though one is a shape and the other a molecule.
