Condensation Reactions

A condensation reaction is an organic reaction in which two smaller molecules combine to form a larger molecule and a much simpler molecule. The simpler molecule produced is often water, which is why the phrase "condensation reaction" is used, while sometimes being referred to as a dehydration. Condensation reactions are important for the creation of many important biological molecules, such as carbohydrates and proteins.

Examples:

1. The reaction of two identical molecules:



When two identical molecules combine to produce a condensation reaction, it is known as intramolecular condensation or self-condensation.

2. The reaction of two different molecules:



When two different molecules combine to produce a condensation reaction, it is known as intermolecular condensation.
