- aldehydes & ketones have a carbonyl group- which is a carbon double bonded to an oxygen atom (C=O)
- aldehyde- when the carbonyl group is at the end of the chain
- ketone- when the carbonyl group is in the middle of the chain or in a ring
- some common ketones are: propanone (acetone) & cyclohexanone
- some common aldehydes are: methanal (formaldehyde), ethanal (acetaldehyde), benzaldehyde
- the carbonyl group is very polar
- this makes aldehydes & ketones up to 3-4 carbons in length miscible in water
- they are less soluble in water and have lower boiling points than alcohols
- more soluble in water and have higher boiling points than ethers & hydrocarbons
- aldehydes & ketones undergo addition reactions at the carbon-oxygen double bond called nucleophilic addition
- this is different from alkene addition because the carbonyl double bond is polar while alkenes have a non-polar pi bond
- ketones can’t be further oxidized but aldehydes can be oxidized to carboxylic acids
