- 5.2: Functional Groups and Classes of Organic Compounds
- Functional groups are structural units that determine the chemical reactivity of a molecule under a given set of conditions. Organic compounds are classified into several major categories based on the functional groups they contain. In the systematic names of organic compounds, numbers indicate the positions of functional groups in the basic hydrocarbon framework.
- 5.5: Identifying the Presence of Particular Groups
- This page explains how to use an infra-red spectrum to identify the presence of a few simple bonds in organic compounds.
- 5.6: The Fingerprint Region
- The fingerprint region is the region to the right-hand side of the diagram (from about 1500 to 500 cm-1) usually contains a very complicated series of absorptions. These are mainly due to all manner of bending vibrations within the molecule.
