Examples
-
And you remember this contrasts with C double bond C, where the addition reactions are electrophilic, not nucleophilic.
-
During the experiment, we observed that the addition reaction produced a new compound without any atoms being lost.
-
The chemistry students studied various types of addition reactions to better understand molecular bonding.

Morphology
The compound is compositionally transparent: 'addition' (the process of adding) modifies 'reaction' (a chemical process), so a learner who knows both words can infer it is a chemical reaction involving addition of one species to another. Although detailed mechanistic knowledge is technical, the basic meaning — a reaction characterized by adding — is directly derivable and follows common noun-noun modification patterns.
Etymology
Addition reaction comes from the simple idea of addition, like putting two Lego blocks together, and reaction, meaning a chemical change. In this image two molecules 'join' and nothing is lost, so the term means 'two or more molecules combine to form a larger molecule'.
