Hydroxyl refers to a functional group in chemistry that consists of an oxygen atom covalently bonded to a hydrogen atom. It is commonly represented by the chemical formula OH. The hydroxyl group is a polar group due to the electronegativity difference between oxygen and hydrogen, making it capable of forming hydrogen bonds. This property significantly influences the physical and chemical behavior of molecules containing this group.

In organic chemistry, the hydroxyl group is the defining characteristic of alcohols. When attached to a carbon atom, it imparts properties such as solubility in water and the ability to participate in various reactions, including oxidation and esterification. For instance, ethanol, with a hydroxyl group attached to an ethyl chain, is a common alcohol known for its solvent properties and its presence in beverages.

Inorganic compounds can also contain hydroxyl groups. For example, hydroxide ions (OH-) are a key component of bases in aqueous solutions. These ions play a crucial role in acid-base chemistry and are found in substances like sodium hydroxide (NaOH). Hydroxyl groups are also present in many minerals and are fundamental to the structure of water. The understanding of hydroxyl groups is essential for comprehending the reactivity and properties of a vast array of chemical substances.
