Identify each organic compound as an alkane, alkene, alkyne, aromatic hydrocarbon, alcohol, ether, aldehyde, ketone, carboxylic acid, ester, or amine, and provide a name for the compound. a.

Verified step by step guidance

1. Identify the functional group present in the compound. The structure shows a carbon double-bonded to an oxygen and single-bonded to a hydrogen, which is characteristic of an aldehyde group.
2. Count the number of carbon atoms in the longest continuous chain that includes the aldehyde group. In this structure, there are five carbon atoms.
3. Determine the root name based on the number of carbon atoms. For five carbon atoms, the root name is 'pent'.
4. Since the compound is an aldehyde, the suffix '-al' is used. Combine the root name with the suffix to form the name 'pentanal'.
5. Verify the structure to ensure there are no other functional groups or branches that need to be considered in the naming process. In this case, the structure is a straight chain with no additional functional groups or branches.
