Also known as condensation reaction, dehydration synthesis is the process of combining small molecules (called monomers) in order to produce larger units (called polymers), following the removal of water (H 2. Definition for Dehydration reaction. A chemical reaction is the process where chemical substances called reactants transform into new substances called products. Step 2: The end result of this nucleophilic attack is the formation of an ether product called sucrose and the loss of water. What are the National Board Certification Areas for Teachers? What Is a Dehydration Reaction in Biology? imaginable degree, area of One of the hardest parts of learning science is keeping up with new terms and definitions. You can predict what happens in these reactions if you think of the word dehydration in everyday terms: loss or removal of water.

It is also considered to be a condensation reaction since two molecules are condensed into one larger molecule with the loss of a smaller molecule (the water.) Sciences, Culinary Arts and Personal This is the reverse of the dehydration synthesis reaction joining these two monomers. During a condensation reaction, two molecules are condensed and water is lost to form a large molecule. Examples of Dehydration Synthesis Dehydration reactions are involved in the industrial production of many substances that are used in daily life, such as polyesters.

Because the newly bonded molecule loses water, this is known as dehydration. 2-Methylcyclohexanol c. 4-Methylcyclohexanol d. 2,2-Dimethylcyclohexanol e. 1,2-Cyclohex. How is the term condensation reaction related to dehydration synthesis? Dehydration reactions are a subset of condensation reactions where two functional groups combine to form a covalent bond along with the release of a small molecule such as water, HCl, methanol or acetic acid.

It is also considered to be a condensation reaction since two molecules are condensed into one larger molecule with the loss of a smaller molecule (the water. As additional monomers join via multiple dehydration synthesis reactions, this chain of repeating monomers begins to form a polymer. Note that the word reactant is singular: we're talking about one molecule of reactant losing one molecule of water.
