Guida verificata passo dopo passo

Examine the structure of cinnamaldehyde provided in the image. Look for characteristic groupings of atoms that correspond to functional groups.

Identify the aldehyde functional group. This group is characterized by a carbon atom double-bonded to an oxygen atom (C=O) and single-bonded to a hydrogen atom (H). In cinnamaldehyde, this group is present at the end of the molecule.

Look for any double bonds between carbon atoms (C=C). These are indicative of an alkene functional group. In cinnamaldehyde, there is a C=C bond in the carbon chain.

Check for the presence of an aromatic ring. An aromatic ring is a cyclic structure with alternating double and single bonds, typically a benzene ring. In cinnamaldehyde, the aromatic ring is part of the structure.

Summarize the functional groups identified: cinnamaldehyde contains an aldehyde group, an alkene group, and an aromatic ring.
