H-C=O
aldehyde general formula
For alkanes
The suffix “-al” indicates the presence of an aldehyde group.
-dial
s added to the end of the parent chain name if there are two aldehydes
aldehyde is given the priority
When an aldehyde molecule also contains alcohol functional group, the
-enal
ending indicates the presence of an alkene
-carbaldehyde
• In cyclic aldehydes, when the carbonyl group is attached to the ring the suffix –
Benzaldehyde
Aromatic aldehyde (an aldehyde functional group is directly attached to the benzene ring) are named after the parent compound
C=O bond has a dipole moment
➢Aldehydes are polar molecules because the
they are polar
aldehyde has higher boiling point because
no hydrogen on the carbonyl group
why cant aldehyde form hydrogen bodns with themselves
