Verified step by step guidance

Understand the concept of dehydration synthesis: It is a chemical reaction that involves the removal of a water molecule to form a new covalent bond between two molecules.

Identify the components involved in dehydration synthesis: Typically, two smaller molecules (often organic compounds) are joined together.

Recognize the role of water in the reaction: During dehydration synthesis, a hydroxyl group (OH) from one molecule and a hydrogen atom (H) from another molecule are removed to form water (H₂O).

Determine the outcome of the reaction: The removal of water facilitates the formation of a new covalent bond between the two molecules, resulting in a larger molecule.

Conclude that the correct answer is the formation of a water molecule and a new covalent bond, as this is the hallmark of a dehydration synthesis reaction.
