Functional Group Identification Practice

Flashcards covering functional group identification for labels A through E on the provided pharmaceutical drug structure.

Pharmaceutical Drug Molecule Diagram

- A complex drug structure used for functional group identification containing labeled sites A through E.

Functional Group at Label A

Carboxylic Acid ($\text{R-COOH}$) - Specifically identifies the hydroxyl oxygen atom. Diagram reference:

Functional Group at Label B

Amide ($\text{R-C(=O)NH-R'}$) - Specifically identifies the carbonyl oxygen atom of the amide linkage. Diagram reference:

Functional Group at Label C

Ester ($\text{R-C(=O)O-R'}$) - Specifically identifies the carbonyl oxygen atom of the ester group. Diagram reference:

Functional Group at Label D

Aromatic Ring / Arene ($\text{C}_6\text{H}_5\text{-R}$) - Represents a benzene / phenyl ring structure. Diagram reference:

Functional Group at Label E

Secondary Amine ($\text{R}_2\text{NH}$) - Specifically identifies the nitrogen atom of the amine group. Diagram reference:
