IUPAC rules for naming an aldehyde:
- • The longest parent carbon chain is identified that includes the carbonyl group.
- • The parent chain name is changed by replacing the suffix “-e” with “-al”.
- • Numbering is done in a way that the carbonyl group is designated as number 1. This is not indicated in the part of the name because for aldehyde, the carbonyl carbon is always numbered 1.
- • The identity and location of substituents if any has to be determined and this information has to be added in front of the IUPAC name.
- • If the carbonyl
functional group is attached to a ring of carbon atoms, the ring is named and “-carbaldehyde” is added as suffix.

Correct IUPAC name for the given aldehyde has to be assigned.
