Mastering the Naming Convention of Cyclic Aldehydes: An Easy-to-Follow Guide

Naming cyclic Aldehydes

Acetaldehyde

When naming cyclic aldehydes, follow these steps:

1. Identify the parent ring: The parent ring is the largest carbon ring that contains the aldehyde group as a substituent.

2. Number the ring atoms: Begin numbering at any point that allows the aldehyde carbon to have the lowest possible number.

3. Identify the aldehyde functional group: The aldehyde functional group has the suffix “-al” and is located on the carbon with the lowest number.

4. Name and number any substituents: If the ring has any substituents, name and number them according to their position on the ring.

5. Combine the names: Start with the number of the aldehyde carbon, then add the name of the parent ring with the suffix “-al” for the aldehyde group.

For example, the cyclic aldehyde with six carbon atoms and an aldehyde group attached to the first carbon is called cyclohexanecarbaldehyde.

Note: If there are multiple aldehyde groups in the ring, the suffix will be “-di-al” for two, “-tri-al” for three, and so on.
