Oksogruppi

Oksogruppi, in Finnish chemistry vocabulary, refer to oxygen-containing functional groups. The term denotes functional groups that include oxygen atoms bonded to carbon or other elements and that play a central role in the reactivity, polarity, and properties of organic and inorganic compounds. It is a broad classification used in textbooks and literature to describe how oxygen affects chemical behavior.

Common examples of oksogruppi include carbonyl groups (C=O) found in aldehydes and ketones, as well as carboxyl groups (–COOH) in carboxylic acids, esters, and amides. Other important oksogruppi are hydroxyl groups (–OH) present in alcohols and phenols, ether linkages (–O–) in ethers, and peroxo groups (–O–O–) in peroxides. In inorganic chemistry, oxo ligands such as metal–oxo (M=O) units are also considered oksogruppi due to their oxygen content.

The presence of oksogruppi influences several properties, including polarity, hydrogen bonding capacity, acidity or basicity, and spectroscopic features. For example, carbonyl groups typically show strong infrared absorption around 1700 cm−1, while hydroxyl groups exhibit broad absorptions in the 3200–3550 cm−1 region. Knowledge of oksogruppi is essential for reaction mechanisms, synthesis planning, and compound identification.

In practice, the term oksogruppi is mainly encountered in Finnish-language texts. In English-language chemistry, researchers more commonly refer to “oxo groups” or, more generally, “oxygen-containing functional groups.” The concept remains a fundamental part of classifying and understanding chemical reactivity across organic and inorganic chemistry.
