Original: Systematic names In the IUPAC system, the name of the alkane chain loses the terminal "e" and adds "ol", e.g. "methanol" and "ethanol".
Simplified: For example, "methyl alcohol" or "ethyl alcohol". IUPAC names are made by taking the name of the alkane chain, removing the last "e", and adding "ol". Examples of this are "methanol" and "ethanol".
