Here are the essential concepts you must grasp in order to answer the question correctly.
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 presence of a carbonyl group (C=O) adjacent to a nitrogen atom. Amides play a crucial role in biochemistry, particularly in the formation of proteins through peptide bonds.

Condensed Structural Formula
A condensed structural formula is a way of representing a chemical structure that shows the arrangement of atoms in a molecule without depicting all the bonds explicitly. It typically groups atoms together to indicate how they are connected, making it easier to visualize the molecular structure. For example, the condensed formula for ethylamine is CH3CH2NH2.

Line-Angle Formula
The line-angle formula, also known as the skeletal formula, is a simplified way of drawing organic molecules where vertices represent carbon atoms and lines represent bonds. This method omits hydrogen atoms attached to carbons, making it easier to visualize complex structures. It is particularly useful for depicting larger molecules and understanding their connectivity quickly.
