addition reaction
Let an agent explain addition reactions and their mechanisms and types, support predicting products and understanding selectivity, describe industrial applications, and support learning in organic chemistry.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain addition reactions and their mechanisms and types, support predicting products and understanding selectivity, describe industrial applications, and support learning in organic chemistry.
A chemical reaction in which two or more molecules combine to form a larger one without loss of atoms, typically by adding reagents across a double or triple bond, in forms such as electrophilic addition to alkenes, nucleophilic addition to carbonyls, conjugate addition, free-radical addition, hydration, hydrogenation, hydroformylation and other hydrofunctionalisations; addition reactions are fundamental in organic synthesis and industrial chemistry and are the reverse of elimination reactions.
What it is for: Reactions combining molecules across multiple bonds.
It can be explain mechanisms and types; support product prediction; describe applications; support learning.
Distinguishing features
No atoms lost
Across multiple bonds
Mechanistic classes
Selectivity rules
What it looks like
Not physical; reaction schemes.
How it is recognised
Two molecules combine into one
Electrophilic, nucleophilic, radical, conjugate
Substitution replaces a group; elimination removes atoms; polymerisation is repeated addition
