Verified step by step guidance1
Understand the concept of functional groups: Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Identify common functional groups in organic chemistry: Some of the most common functional groups include hydroxyl (-OH), carboxyl (-COOH), amino (-NH2), and methyl (-CH3) groups.
Recognize the hydroxyl group: The hydroxyl group (-OH) is a common functional group found in alcohols and is characterized by an oxygen atom bonded to a hydrogen atom.
Differentiate between ions and functional groups: Ions like sulfate (SO4^2-), ammonium (NH4^+), and chloride (Cl^-) are charged species and are not typically considered functional groups in organic molecules.
Conclude that the hydroxyl group is the correct answer: Based on the definition and examples of functional groups, the hydroxyl group (-OH) is indeed a functional group commonly found in organic molecules.
