condensation reaction
Let an agent explain condensation reactions and their kinds, relay mechanisms and examples from chemistry references, describe roles in biochemistry and polymer manufacture, and distinguish condensation from addition and hydrolysis.
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 condensation reactions and their kinds, relay mechanisms and examples from chemistry references, describe roles in biochemistry and polymer manufacture, and distinguish condensation from addition and hydrolysis.
A chemical reaction in which two molecules or parts of a molecule combine to form a larger molecule with the loss of a small molecule such as water, ammonia or an alcohol, including dehydration reactions that eliminate water, the aldol condensation that forms carbon-carbon bonds, esterification and amide formation, and polycondensation that builds polymers such as nylon and polyesters, demonstrated in the nylon rope trick; condensation reactions are central to organic synthesis, polymer chemistry and biochemistry, where they join monomers into proteins, nucleic acids and polysaccharides.
What it is for: Building larger molecules from smaller ones.
It can be explain the reaction type and kinds; relay mechanisms and examples; describe biochemical and industrial roles; distinguish from related reactions.
Distinguishing features
Loss of a small molecule
Bond formation between reactants
Reversible by hydrolysis
Basis of step-growth polymers
What it looks like
Not a visible object; reaction schemes and, in demonstrations, a polymer film pulled from an interface.
How it is recognised
Combination reaction losing a small molecule
Dehydration, aldol, esterification, polycondensation
Addition reactions lose nothing; hydrolysis is the reverse

What the second pass must settle
- Should aldol condensation and polycondensation be separate primary entries?
- How should reference definitions be linked?
- The registry entry has merged aliases naming a demonstration and specific reaction types; should they be split off?
