Types of Chemical Reactions Concept Map Guide
A types of chemical reactions concept map sorts reactions by what happens to the atoms and bonds. The five main classes are synthesis, where substances combine into one product; decomposition, where one compound breaks into simpler substances; single replacement, where one element displaces another; double replacement, where ion partners swap; and combustion, where a substance reacts rapidly with oxygen. Redox reactions, which involve electron transfer, cut across several of these classes.
- Synthesis: two or more reactants form one compound, such as 2H2 + O2 forming water.
- Decomposition: one compound breaks into two or more products, often with heat or light.
- Single replacement: a more reactive element displaces another from a compound.
- Double replacement: ions in two compounds swap partners, often forming a precipitate or gas.
- Combustion: fuel reacts with oxygen, releasing heat and typically forming CO2 and water.
Use the map to check whether an equation is synthesis, decomposition or another type, then revise by quizzing yourself. CogniGuide can build a personalized version from your own chemistry notes.

Chemical Reactions Concept Map Questions
Common questions about classifying reactions and building your own map.
How many main types of chemical reactions are there?
Most introductory courses teach five main types: synthesis, decomposition, single replacement, double replacement and combustion. Some courses also cover acid-base neutralization and redox as separate categories, since they overlap with the others.
How do you tell a synthesis reaction from a decomposition reaction?
In synthesis, two or more reactants combine into a single product, so the number of products is fewer than the reactants. In decomposition, one reactant breaks into two or more simpler products. Looking at the arrow direction and counting substances usually settles it.
Which file types can I use to make a chemistry map?
You can upload a PDF, Word (DOCX) or PowerPoint (PPTX) file, a text or Markdown file, or an image. You can also type a topic instead.
Can I turn my reaction map into a quiz?
Yes. Any CogniGuide map can be turned into a quiz to test yourself. The free plan includes 5 creations a week with no payment needed.
