Aromatic aldehydes are named as substituted benzaldehydes. The IUPAC-accepted common name for the simplest aromatic aldehyde is benzenecarbaldehyde, but benzaldehyde is also accepted by IUPAC.
How are aromatic aldehydes named in IUPAC nomenclature, and what is the IUPAC-accepted common name for the simplest aromatic aldehyde?

Aromatic aldehydes are named in IUPAC nomenclature by designating the benzene ring as the parent hydrocarbon and adding the suffix “-carbaldehyde” to indicate the presence of the aldehyde group. The position of the aldehyde group is specified by numbering the carbons on the benzene ring. The IUPAC-accepted common name for the simplest aromatic aldehyde is “benzaldehyde.” It is derived from the systematic name “benzenecarbaldehyde,” with the benzene ring as the parent and the carbaldehyde suffix indicating the aldehyde functional group. “Benzaldehyde” is widely used in both IUPAC and common nomenclature for this compound.
