C5H11OH represents an alcohol.

To determine the representation of C5H11OH, we need to identify its functional group, which refers to the specific arrangement of atoms in a molecule that determines its chemical properties.

C5H11OH is a chemical formula, where C represents carbon, H represents hydrogen, and OH represents the hydroxyl functional group.

Therefore, C5H11OH represents an alcohol. Alcohols are organic compounds that contain the hydroxyl functional group (-OH) bonded to a carbon atom. This functional group gives alcohols their characteristic properties, such as the ability to form hydrogen bonds and their solubility in water.
