Final answer:
A condensation reaction is also known as a dehydration synthesis reaction, where two molecules combine to form a single molecule and release water as a byproduct.
Step-by-step explanation:
A condensation reaction is also known as a dehydration synthesis reaction. In this type of reaction, two molecules combine to form a single molecule while releasing a molecule of water as a byproduct. Condensation reactions are commonly used in the formation of polymers, such as when monomer molecules link together to form a larger polymer chain.
