Greetings,
This post focuses on Aldehydes; their structure and naming methods.
The Aldehyde is another type of organic compound formed from a slight modification of a hydrocarbon. The aldehyde functional group is always built at the end carbon of a hydrocarbon. Of course, the latter statement doesn't really apply to methane and ethane molecules, as they do not consist of a "middle" carbon atom.
Aldehydes are highly reactive compounds, often used to create a hydrocarbon "bridge" between molecules able to lose a hydrogen atom connected to a carbon. An example of such a molecule is salicylic acid (an aromatic weak acid also consisting of a hydroxyl group).
The carbon of the aldehyde functional group (stated as, "C bond H, double-bond O ") is counted as part of the parent hydrocarbon for naming purposes. Additionally. the aldehyde group is always at the end of the molecule, so its location does not need to be indicated. For naming, we only need to indicate the number of carbons in the parent hydrocarbon and a way to note that we have an aldehyde functional group. The following chart shows examples of molecular structures, Lewis formulas, and naming conventions.
One must be careful because the IUPAC name of an aldehyde closely resembles that of an alcohol. Chemists working in a lab are more likely to refer to aldehydes using their stock names, as indicated above.
That's all for this post. As always, thank you for reading!
