A double exchange reaction is where the two reactants trade fragments: AB + CD = AC + BD. Both are exchanging fragments, hence "double reaction", for example:
AgNO3(aq) + NaCl(aq) = AgCl(s) + NaNO3(aq)
or
NaClO4 + NH4Cl = NH4ClO4 + NaCl
Ion-exchange reaction or just exchange reaction.
other name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
no it is a direct combination reaction
No, a chemical reaction involving different molecules does not involve a direct exchange of atoms or positions between the molecules. Each molecule in a reaction follows its specific reaction pathway based on the reactivity and bonding preferences of the atoms within it.
Outside of a particle accelerator they aren't. It is a nuclear reaction although an actual exchange of protons would be very unlikely (depending on what you mean by "exchange").

polymeranalogous reaction end-coupling reaction interchain exchange reaction
This type of reaction is called a double displacement reaction or a metathesis reaction. It involves the exchange of ions between two compounds to form two new compounds.
Partners are exchanged in a double replacement reaction.
In the English language this reaction is called counter-ion exchange double displacement reaction.
In the English language this reaction is called counter-ion exchange double displacement reaction.
This reaction is called "metal-metal exchange reaction".
