a formyl group
They have the same functional group.
aldehyde
An amino aldehyde is an organic compound containing both an amino and an aliphatic aldehyde functional group.
The functional group for C2O2H4 is an aldehyde group. This is because there are two carbon atoms in the compound, which form a carbonyl group (C=O), and a hydrogen atom bonded to one of the carbons. This structure classifies it as an aldehyde.
Aldehyde and ketones .
The functional group of citral is the aldehyde (alkanal) group. It has the structure -CHO
Carbonyl
Carbonyl
Carbonyl
The functional groups in vanillin are a hydroxyl group (-OH) and an aldehyde group (-CHO).
aldehyde
They have the same functional group.
Carbonyl
The functional group of biphenyl is aromatic ring, benzene.
From its structure, we can see that vanillin does not have a ketone functional group, but it has an aldehyde. It also has a phenol and ether functional group. For that reason, I wouldn't categorize is as just an aldehyde.
An amino aldehyde is an organic compound containing both an amino and an aliphatic aldehyde functional group.
An aldehyde contains a carbonyl group, which is a carbon atom double-bonded to an oxygen atom.
