Identify the functional group in each compound. Both structures contain an aldehyde group, which is characterized by the presence of a carbonyl group (C=O) bonded to a hydrogen atom.
For the first compound, identify the longest carbon chain that includes the aldehyde group. The chain consists of three carbon atoms, making it a propanal derivative.
In the first compound, note the presence of a phenyl group (Ph) and a methyl group (CH₃) attached to the second carbon of the chain. This makes it a 2-phenyl-2-methylpropanal.
For the second compound, identify the longest carbon chain that includes the aldehyde group. The chain consists of four carbon atoms, making it a butanal derivative.
In the second compound, note the presence of a phenyl group (Ph) attached to the second carbon of the chain. This makes it a 2-phenylbutanal.
