The three types of reactions that yield a product that is a chemically bonded combination of reactants are:
- Synthesis - In this type of reaction, two or more reactants combine to form a single product.
- Polymerization - This involves the joining of small molecules (monomers) to form a larger complex structure (polymer), resulting in a chemically bonded product.
- Oxidation - While generally associated with the transfer of electrons, certain oxidation reactions can result in the formation of new compounds which are chemically bonded structures, especially when combined with reduction reactions in redox processes.
Among the options provided, "oxidation, synthesis, polymerization" is the best choice, as it encompasses reactions that inherently lead to the formation of new chemical compounds through bonding.
So, the answer is: oxidation, synthesis, polymerization.
