Draw structures of the amides that can be made from the following reactants:


a. CH₃NH₂ + (CH₃)₂CHCOOH →?

Verified step by step guidance

1. Identify the functional groups in the reactants: CH₃NH₂ is a primary amine and (CH₃)₂CHCOOH is a carboxylic acid.
2. Understand that an amide is formed when an amine reacts with a carboxylic acid, resulting in the elimination of water (H₂O).
3. Write the general reaction for amide formation: RCOOH + R'NH₂ → RCONHR' + H₂O.
4. Apply the general reaction to the given reactants: (CH₃)₂CHCOOH (carboxylic acid) reacts with CH₃NH₂ (amine) to form the amide (CH₃)₂CHCONHCH₃.
5. Draw the structure of the resulting amide: The carbonyl carbon of the carboxylic acid is bonded to the nitrogen of the amine, forming the amide linkage.

Key Concepts

Amides

Amides are organic compounds derived from carboxylic acids where the hydroxyl group (-OH) is replaced by an amine group (-NH₂, -NHR, or -NR₂). They are characterized by the functional group -C(=O)N-, and are important in various biological processes, including protein synthesis. Understanding the structure of amides is crucial for predicting their reactivity and properties.

Carboxylic Acids

Carboxylic acids are organic acids characterized by the presence of a carboxyl group (-COOH). They are key reactants in the formation of amides through a condensation reaction with amines, where water is eliminated. Recognizing the structure and reactivity of carboxylic acids is essential for understanding how they can be transformed into amides.

Condensation Reaction

A condensation reaction is a chemical process where two molecules combine to form a larger molecule, accompanied by the loss of a small molecule, often water. In the context of amide formation, the reaction between an amine and a carboxylic acid results in the formation of an amide and water. This concept is fundamental for predicting the products of the given reactants.
