Is amide formation a condensation reaction?

Amidation. An amidation reaction is a condensation reaction in which reactants (typically an amine and carboxylic acid) combine to produce an amide. The addition of ammonia (NH3) to a carboxylic acid forms an amide, but the reaction is very slow in the laboratory at room temperature.

What occurs during a condensation reaction?

Condensation reaction: A reaction in which two or more molecules combine to form a larger molecule, with the simultaneous loss of a small molecule such as water or methanol. While this occurs in many reactions, the term is usually reserved for reactions in which a new carbon-carbon bond is formed.

What are the products of a condensation reaction?

Products of condensation reactions include ethers, acetals, esters, imines, and amides. We now consider condensation reactions that yield polymers. Two functional groups are required in a monomer so that after one functional group reacts, the other is available to link to another monomer.

What condenses with an amine to form an amide?

Amines and carboxylic acids can combine in a condensation reaction to form amides.

What is amine condensation?

When two amino acids combine in a condensation reaction, a covalent bond forms between the amine nitrogen of one amino acid and the carboxyl carbon of the second amino acid. A molecule of water is then removed as a second product.

Can carboxylic acid condense with amine?

We find that a suite of amides (12 examples) are readily synthesized through a direct condensation between amines and carboxylic acids, with an amide yield of up to 90% over a timescale of hours.

What substance is removed during a condensation reaction?

A condensation reaction is a reaction in which two molecules combine to form a single molecule. A small molecule, often water, is usually removed during a condensation reaction.

What are the products of a condensation reaction between a primary amine and a carboxylic acid?

What are the products of a condensation reaction between a primary amine and a carboxylic acid? e. an ammonium cation and a carboxylate anion.

What is one product of a condensation reaction between two amino acids?

Amino acids can be linked by a condensation reaction in which an ―OH is lost from the carboxyl group of one amino acid along with a hydrogen from the amino group of a second, forming a molecule of water and leaving the two amino acids linked via an amide—called, in this case, a peptide bond.

Why secondary amine is used in Mannich reaction?

It can be noted that the Mannich reaction can also be considered as a condensation reaction. The reason primary/secondary amines (or NH3) are used for the activation of the formaldehyde is that tertiary amines would lack the N-H proton which is required for the formation of the enamine intermediate.

What happens when amines react with carboxylic acid?

The reaction between amines and carboxylic acids to form amides is biologically important. It is through this reaction that amino acids (molecules containing both amine and carboxylic acid substituents) link together in a polymer to form proteins.

Why is the formation of a protein from amino acids called a condensation reaction?

Proteins are formed in a condensation reaction when amino acid molecules join together and a water molecule is removed. The new bond formed in protein molecules where amino acids have joined (-CONH) is called an amide link or a peptide link.
