What are the different types of chemical reactions?
4 Main Types of Chemical Reactions 1 Synthesis reaction (also known as a direct combination reaction)#N#In this reaction, reactants combine to form a more complex product. Often there are two or more reactants with only a single product. The general reaction takes the form:#N#A + B → AB 2 Decomposition reaction (sometimes called an analysis reaction)#N#In this kind of reaction, a molecule breaks into two or more smaller pieces. It's common to have one reactant and multiple products. The general chemical reaction is:#N#AB → A + B 3 Single displacement reaction (also called a single replacement reaction or substitution reaction)#N#In this type of chemical reaction, one reactant ion changes place with another. The general form of the reaction is:#N#A + BC → B + AC 4 Double displacement reaction (also called a double replacement reaction or metathesis reaction)#N#In this type of reaction, both cations and anions exchange places, according to the general reaction:#N#AB + CD → AD + CB
