Understanding the Differences in Chemical Properties and Reactivity Between Aldehydes and Ketones

Aldehyde vs. Ketones Terminal group

Formaldehyde

Aldehydes and ketones are two types of organic compounds that contain a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. The main difference between aldehydes and ketones lies in the placement of the carbonyl group.

Aldehydes have the carbonyl group at the end of a carbon chain, while ketones have the carbonyl group in the middle of a carbon chain. This results in different chemical properties and reactions for these compounds.

Aldehydes are typically more reactive than ketones because of the presence of a hydrogen atom on the carbonyl carbon, which makes it more susceptible to nucleophilic attack. This is seen in reactions such as reduction, where aldehydes are easily converted to primary alcohols, while ketones are more difficult to convert to secondary alcohols.

On the other hand, ketones are more stable than aldehydes due to the absence of a hydrogen atom on the carbonyl carbon. This makes them less susceptible to oxidation and other reactions that involve attack on the carbonyl carbon.

In summary, the main difference between aldehydes and ketones lies in the placement of the carbonyl group, which affects their chemical reactivity and stability. Aldehydes have the carbonyl group at the end of the carbon chain, while ketones have it in the middle.
