Aromatherapy Certification Practice Test 2025 – Comprehensive Exam Prep

The classification of essential oils as ketones is determined by their chemical structure, specifically the presence of a ketone functional group. Ketones are characterized by a carbonyl group (C=O) connected to two carbon atoms.

The choice that includes Peppermint, Rosemary, Spike Lavender, and Vetiver is correct because these oils contain notable ketones. For instance, Peppermint is known for its high menthol content, which is a type of ketone. Rosemary contains various ketones, including camphor. Spike Lavender has prominent ketones as well, contributing to its flavor and aroma. Vetiver is another essential oil that features ketones within its chemical profile, specifically compounds that provide its earthy scent.

The other choices include oils that may contain different types of chemical compounds unrelated to ketones, such as terpenes or alcohols, which would not classify them under ketones. This distinction is vital for understanding the properties and therapeutic applications of various essential oils in aromatherapy.
