Reaktionernas

Reaktionernas is the genitive form of the definite plural noun reaktionerna (the reactions) in Swedish. It translates roughly as "of the reactions" or "the reactions’" and is used to indicate possession or association with multiple reactions. The base plural is reaktioner (reactions).

To form it, the definite plural is reaktionerna, to which the possessive suffix -s is added: reaktionerna + s = reaktionernas. This is a standard Swedish possessive construction and does not require an apostrophe. It differs from the indefinite plural reaktioner and from the non-possessive definite plural reaktionerna.

In use, reaktionernas appears in scientific and academic writing, textbooks, and descriptive prose when discussing properties or outcomes related to several reactions. Examples include "reaktionernas hastighet" (the speed of the reactions) or "reaktionernas mekanismer" (the mechanisms of the reactions). The form is a routine element of Swedish grammar for expressing possession with plural nouns in formal and technical contexts.
