In chemistry, an alcohol exists when a hydroxyl group, a pair of oxygen and hydrogen atoms, replaces the hydrogen atom in a hydrocarbon. Alcohols bind with other atoms to create secondary alcohols. These secondary alcohols are the three types of alcohol that humans use every day: methanol, isopropanol, and ethanol.
