Which of the following is not true regarding dehydration synthesis? 1) It requires energy.
2) It results in the breakdown of large molecules into smaller mol
3) As chemical bonds are formed during this process, it results in
molecule of water.
4)
It uses small molecules needed for this process that result fror
of food.
5) It is also known as a condensation reaction.

It results in the breakdown of large molecules into smaller molecules is not

true regarding dehydration synthesis.

Dehydration synthesis is also known as a condensation reaction as it

involves the formation of a large molecule from two or more smaller

molecules through the formation of chemical bonds.

It requires energy and is characterized by the formation of water molecules

which makes option 2 the most appropriate choice.

2) It results in the breakdown of large molecules into smaller molecules

Explanation:

A dehydration reaction or dehydration synthesis is a reaction that involves the loss of a water molecule as one of the products. As the name implies (de- remove, hydrate-water), water (H20) is released as chemical covalent bonds forms between the joining small molecules.

Small molecules called monomers are joined together to synthesize a much larger molecule called Polymer. Since it involves the joining or condensation of two small molecules, dehydration synthesis is also referred to as CONDENSATION reaction.

Dehydration synthesis builds up large molecules from small ones, hence, it is an endothermic process i.e. requires energy to occur. Hence, the untrue statement in the question is that dehydration synthesis results in the breakdown of large molecules into smaller molecules because it is the opposite (synthesis of large molecules from small ones).
