Verified step by step guidance

1. Identify the reactants involved in the formation of an amide. Typically, an amide is formed from the reaction between a carboxylic acid and an amine.
2. Determine the functional groups present in the reactants. A carboxylic acid contains a carboxyl group (-COOH), and an amine contains an amino group (-NH2).
3. Recognize that during the formation of an amide, the hydroxyl group (-OH) from the carboxylic acid and a hydrogen atom from the amine are removed to form water (H2O).
4. Combine the remaining parts of the carboxylic acid and amine to form the amide linkage, which is characterized by the -CONH- group.
5. Draw the condensed structural formula or line-angle formula of the resulting amide, ensuring to represent the -CONH- linkage clearly.

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-, which plays a crucial role in their chemical properties and reactivity. Understanding the structure of amides is essential for drawing their condensed structural or line-angle formulas.

Condensed Structural Formula

A condensed structural formula provides a simplified representation of a molecule, showing the arrangement of atoms and the connectivity between them without depicting all the bonds explicitly. In the context of amides, this formula highlights the carbonyl group and the attached amine group, allowing for a clearer understanding of the molecule's structure and functional groups.

Line-Angle Formula

The line-angle formula, also known as the skeletal formula, is a shorthand representation of organic molecules where vertices represent carbon atoms and lines represent bonds. This method simplifies the drawing of complex structures, making it easier to visualize the connectivity and geometry of the molecule, particularly useful for amides formed in chemical reactions.
