Aldehyde vs. Ketones Terminal group
Formaldehyde
Aldehydes and ketones are two types of carbonyl compounds that share a similar functional group: a carbon-oxygen double bond (C=O). However, the difference lies in the location of the carbonyl group within the molecule.
Aldehydes have the carbonyl group (-CHO) located at the end of the carbon chain. These compounds are characterized by their strong odor and are commonly found in fragrances and flavorings. Examples of aldehydes include formaldehyde, acetaldehyde, and benzaldehyde.
On the other hand, ketones have the carbonyl group (-CO-) located within the carbon chain. They are usually less reactive than aldehydes and have a characteristic sweet smell. Some examples of ketones include acetone, butanone, and cyclohexanone.
In summary, the main difference between aldehydes and ketones lies in the location of the carbonyl group within the molecule. Aldehydes have (-CHO) at the end while ketones have (-CO-) within the molecule.
