Combination reaction

In chemistry, a combination reaction is a chemical reaction in which two or more reactants combine or bond to form a new single product. The generic combination reaction, in which two reactants, A and B, combine to form a single product C, is typically written as:
Example
Description

A + B → CThe atomic compositions of the reactants, A and B, are modified.
A + B → ABThe reactants, A and B, retain their atomic geometry.
A + B + C → ABCThree reactants, A, B, and C, combined into a singe unit, while retaining their internal atomic geometry.

In the older eighteenth century affinity reaction nomenclature this reaction likely has a name, similar to a single elective affinity reaction, but the name needs to be tracked down.

Classification
The five basic or rather simplest chemical reactions are listed below: [1]

Type
Name (modern chemistry)
SynonymsName (affinity chemistry)
Formula

1.Combination reaction

A + B → C
2.Decomposition reactionDebonding reaction
Dissolution reaction

A → B + C

3.Substitution reaction
single elective affinityAB + C → AC + B

4.Double substitution reaction
double elective affinityAB + CD → AC + BD
5.Combustion reaction

Fuel + Oxidant → Product + H2O


There are many other varieties of reactions than these five.
