What is the term for the removal of water from a compound?

The removal of water from a compound is known as dehydration. This process involves the elimination of water molecules, which can lead to changes in the chemical structure and properties of the compound. Dehydration is a crucial concept in various scientific fields, including chemistry and biology, as it influences reactions, structural integrity, and the stability of compounds.

In certain chemical reactions, dehydration can lead to the formation of double bonds or new structures by removing water. This process is essential in creating certain organic compounds and can also occur in biological processes, such as the drying of tissues.

The other terms relate to different concepts: hydration involves the addition of water to a substance, condensation generally refers to the process where vapor converts into liquid, and evaporation is the process of a liquid turning into vapor. Each of these terms describes distinct phenomena that do not apply to the specific process of removing water from a compound.
