The hydroxyl group, -OH, can occur in three different envirnments in organic molecules, alcohols, phenols and carboxylic acids.
Alcohols contain the hydroxyl functional group (-OH) attached to an aliphatic carbon chain.
Phenols are compounds that have one or more -oh groups attached directly to a benzene ring. Although phenols look simila to alcohols, their chemical reactions are different.
Test for phenols - neutral iron(iii) chloride
Alcohols, phenols and carboxylic acids are all weak acids.
