WebSimilarities between the reactions. Comparing the structures of water, ethanol and phenol. Each substance contains an -OH group. In water, this is attached to a hydrogen atom. In an alcohol, it is attached to an alkyl group - shown in the diagrams below as "R". In phenol, it is attached to a benzene ring. Phenol is C 6 H 5 OH. 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. earnease.net scam
