Verified step by step guidance1
Identify the definition of a functional group: A functional group is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Review the options provided: Nitrogen gas (N2), Chloride ion (Cl-), Hydroxyl group (-OH), and Sodium ion (Na+).
Understand that functional groups are typically part of larger organic molecules and are not standalone ions or diatomic molecules.
Recognize that the hydroxyl group (-OH) is a common functional group found in organic molecules, such as alcohols, and is responsible for their chemical properties.
Conclude that the hydroxyl group (-OH) is the correct answer as it fits the definition of a functional group commonly found in organic molecules.
