Question

Define various types of chemical reactions

Answer 1

common classification scheme recognizes four major reaction types:

(1) combination or synthesis reactions

(2) decomposition reactions

(3) substitution or single replacement reactions

(4) metathesis or double displacement reactions

• combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product)
• Decomposition reaction is a chemical reaction in which two or more products are formed from a single reactant
• Substitution reaction (also known as single displacement reaction or single substitution reaction) is a chemical reaction during which one functional group in a chemical compound is replaced by another functional group.
• Metathesis reactions are the Reactions in which two compounds react to form two new compounds, with no changes in oxidation number.
