C) polymerization reactions.
D) the addition of an amino group.

Question

Quizplus · Accepted Answer

Hydrolysis reactions can reverse the results of dehydration reactions by breaking apart the covalent bonds that were formed during dehydration. This occurs when a water molecule is split into a hydrogen ion and a hydroxide ion, and the hydrogen and hydroxyl groups are then added back to the original molecules to form new covalent bonds. Condensation reactions involve the formation of water molecules, which is the opposite of what happens during dehydration, so they do not reverse dehydration reactions. Polymerization reactions involve the formation of large, complex molecules from smaller building blocks, so they also do not reverse dehydration reactions. The addition of an amino group would not necessarily reverse dehydration reactions, as this type of group is not involved in the covalent bonds that form during dehydration.
