Propose structures and draw condensed formulas for molecules that meet the following descriptions.
(c) A compound with formula C₂H₅NO₂ that is both an amine and a carboxylic acid

Verified step by step guidance

1. Step 1: Identify the functional groups mentioned in the problem. An amine functional group has the general formula -NH2, and a carboxylic acid functional group has the general formula -COOH.
2. Step 2: Start by drawing the backbone of the molecule with two carbon atoms, as indicated by the formula C2. Connect these two carbon atoms with a single bond.
3. Step 3: Attach the amine functional group (-NH2) to one of the carbon atoms. This uses up one hydrogen atom and the nitrogen atom.
4. Step 4: Attach the carboxylic acid functional group (-COOH) to the other carbon atom. This uses up the oxygen atoms and one hydrogen atom.
5. Step 5: The remaining hydrogen atoms (H2) are attached to the carbon atoms to complete the molecule. Each carbon atom should have four bonds in total, and the nitrogen atom should have three bonds in total.

Key Concepts

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In this case, the compound C2H5NO2 must contain both an amine group (-NH2) and a carboxylic acid group (-COOH), which dictate its reactivity and properties.

Condensed Formulas

A condensed formula is a way of representing a chemical compound that shows the arrangement of atoms in a simplified manner. It provides information about the types and numbers of atoms present, as well as their connectivity, without depicting the full structural formula. For the given compound, the condensed formula will reflect the presence of both the amine and carboxylic acid functional groups.

Isomerism

Isomerism refers to the phenomenon where compounds with the same molecular formula can have different structures or arrangements of atoms. In the case of C2H5NO2, understanding isomerism is crucial as the compound can exist in different forms, such as amino acids, which can influence its properties and biological functions.
