WebAlcohols and phenols An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H 2 O, is the simplest and most common example. If one hydrogen atom is removed from a water molecule, a hydroxyl functional group (―OH) is generated. When a hydroxyl group is joined to an alkane framework, an alcohol such as ethanol, is produced.
