The alkanol is known in organic chemistry, a hydrocarbon group, that of the alkanes ( saturated hydrocarbons ) derived. A functional group all alkanols having one or more hydroxyl groups. Analogous compounds derived from unsaturated hydrocarbons, hot alkenols (with one or more double bonds ) and alkynols (with one or more triple bonds ). The word alkanols comes from the IUPAC nomenclature.
The terms alcohol and alkanol are not identical in meaning. The term alcohol refers to the functionality of the hydroxyl group, while the term alkanol beyond even the saturated nature of the alkyl group having defined.
Alkanols having two hydroxy groups are called alkane diols ( the simplest example: ethylene glycol ), those with three hydroxyl groups are alkanetriols ( the simplest example is glycerol).
