What is the general formula of alkanol


General formula of the alkanols with the blue labeled hydroxy group as a functional group. The radical R stands for an alkyl radical. For example, if R is a methyl group, the result is methanol, if R is an ethyl group, the result is ethanol (colloquially: "alcohol").

As Alkanols In organic chemistry, one describes a group of substances that is derived from alkanes (saturated hydrocarbons). All alkanols have one or more hydroxyl groups as a functional group. Analogous compounds derived from unsaturated hydrocarbons are called alkenols (with one or more double bonds) and alkynols (with one or more triple bonds). The word Alkanols comes from the IUPAC nomenclature.[1]

The terms alcohol and Alkanol are not synonymous. The term alcohol relates to the functionality of the hydroxyl group, while the term alkanol also defines the saturated character of the alkyl radical.

Alkanols with two hydroxyl groups are called alkanediols (simplest example: ethylene glycol), those with three hydroxyl groups are alkanediols (simplest example is glycerine).
