A synthesis reaction is the joining together of two reactants (compounds) to produce a complex product (compound). Sometimes synthesis reactions can result in the formation of more than one product, as we will see shortly with the process of photosynthesis.
A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. Direct Combination or Synthesis Reaction. 2  In a synthesis reaction two or more chemical species combine to form a more complex product. 3  A + B â AB. 4  The combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction :
