atomiryhmän

Atomiryhmään is the illative form of the Finnish noun atomiryhmä, which means a functional group in chemistry. Atomiryhmä refers to a specific arrangement of atoms within a molecule that largely determines its chemical properties and reactivity. The illative form atomiryhmään is used to express movement toward or introduction into that group, for example in reaction descriptions or mechanistic explanations.

In chemical writing, atomiryhmä is the term for a recognized group of atoms that behaves as a unit in reactions, such as hydroxyl, carbonyl, or amino groups. The illative case atomiryhmään appears when describing processes where something is directed toward or interacts with that group, such as an electrophilic attack or the addition step that targets the functional group. The form is typical of formal Finnish technical prose and may be found in textbooks, research articles, and reaction schemes.

Linguistically, atomiryhmään illustrates how Finnish uses case inflection to express spatial and directional relationships. It is contrasted with other forms like atomiryhmässä (in the functional group) and atomiryhmää (accusative/genitive-like contexts in some constructions). When writing about chemistry in Finnish, choosing the correct illative form helps clarify the directionality of a reaction step or the locus of chemical change.
