Understand what a terpene is: Terpenes are a large and diverse class of organic compounds produced by plants, typically constructed from isoprene units (C5H8). They often have structures based on multiples of five carbon atoms.
Identify the key structural features of terpenes: Terpenes are made up of repeating isoprene units linked head-to-tail, and common examples include monoterpenes (C10), sesquiterpenes (C15), and diterpenes (C20).
Analyze each compound given: Benzaldehyde is an aromatic aldehyde, Phenol is an aromatic compound with a hydroxyl group, Acetone is a simple ketone, and Limonene is a hydrocarbon with a structure based on two isoprene units, making it a monoterpene.
Match the compound to the terpene definition: Since Limonene consists of two isoprene units and is commonly found in citrus oils, it fits the classification of a terpene.
Conclude that among the options, Limonene is the compound classified as a terpene due to its isoprene-based structure.
