Exploring Methanal (Formaldehyde) – The Simplest Aldehyde: IUPAC Nomenclature vs Common Name

Aldehyde Nomenclature: Methanal

Propionaldehyde

Methanal is the simplest aldehyde, also known by its common name, formaldehyde. In the IUPAC nomenclature system, the prefix “meth-” indicates one carbon atom in the molecule, and the suffix “-al” indicates that the compound is an aldehyde.

Therefore, the IUPAC name of methanal is “methanaldehyde”. However, the preferred name for this compound is simply “formaldehyde”.

It is important to note that the common name “formaldehyde” is widely used in various fields, including industry, chemistry, and medicine. Therefore, using the IUPAC name “methanaldehyde” can cause confusion and is not commonly used in practice.
