Naming Aldehydes

21. Aldehydes and Ketones: Nucleophilic Addition / Naming Aldehydes / Problem 1

Explain why a locant is not required to identify the primary functional group when naming aldehydes.

A

Since the aldehyde group is always at the end of the parent chain, it is always numbered as "1" and its locant is not required to be specified.

B

Specifying the locant unnecessarily increases the length of the name, so the locant does not need to be specified.

C

Identifying the locant messes up the numbering for other possible substituents in the compound.

D

None of the above.
