Greetings,
This post continues on with carboxylic acids; otherwise known as organic acids. The functional group for this compound class always includes the terminal atom of a carbon chain. Consequently, the location of the carboxylic group does not need to be noted in the compound name. Like other compounds, the organic acids have common stock names and formal IUPAC names. Chemists working in a lab, would normally speak of organic acids using their stock names. Reference to organic acid names in official documents, such as journal publications, would likely use the formal IUPAC names. The following chart summarizes structures and corresponding names for some of the lowest molecular weight carboxylic acids.
As you can see from the chart, the structures of organic acids are all very similar. Even so, the physical and chemical properties between them can vary greatly. For example, small amounts of acetic acid can be safely consumed, but one would not dare consume even very small quantities of formic acid!
Notice, too, that the IUPAC names are very "systematic"; being derived from the carbon chain number prefix and the "-anoic" suffix to designate an organic acid compound type. The stock names, on the other hand, can vary greatly from the formal names because these names indicate natural sources; often using Latin or Greek names of plant and animal sources.

That's all for now. As always, thank you for reading!
