In what type of reactions are chemical bonds in a molecule broken by the addition of a water molecule?

Question

Quizplus · Accepted Answer

Hydrolysis breaks chemical bonds in a molecule by the addition of a water molecule, usually resulting in the separation of larger molecules into their smaller subunits. Condensation, on the other hand, forms bonds by the removal of a water molecule. Covalent bonds are not broken or formed by the addition or removal of molecules, but rather by the sharing of electrons between atoms. Reduction involves the gain of electrons, but it does not necessarily result in the breaking of chemical bonds.
