Common Names of Aldehydes
– An aldehyde has a terminal functional group due to the one hydrogen- Ketone has two alkyl groups so it’s never a terminal group.
Aldehydes are a class of organic compounds that have the carbonyl functional group (C=O) at the end of a carbon chain. Some of the common names of aldehydes according to the number of carbon atoms present in the molecule are:
1. Methanal (formaldehyde): CH2O
2. Ethanal (acetaldehyde): CH3CHO
3. Propanal (propionaldehyde): CH3CH2CHO
4. Butanal (butyraldehyde): CH3(CH2)2CHO
5. Pentanal (valeraldehyde): CH3(CH2)3CHO
6. Hexanal (caproaldehyde): CH3(CH2)4CHO
7. Heptanal (heptaldehyde): CH3(CH2)5CHO
8. Octanal (octaldehyde): CH3(CH2)6CHO
9. Nonanal (nonaldehyde): CH3(CH2)7CHO
10. Decanal (decanaldehyde): CH3(CH2)8CHO
These aldehydes are used in various industrial and laboratory applications including as solvents, preservatives, flavoring agents, and chemical intermediates in the synthesis of other organic compounds.
