Which compound is associated with the smell of eucalyptus, fresh, minty?

• A. Camphor
• B. Eucalyptol
• C. Limonene
• D. Menthol

Answer: (B)

The scent clue points to a compound that defines eucalyptus’s fresh, minty aroma. That compound is eucalyptol, also known as 1,8-cineole. It is the dominant constituent in many eucalyptus oils and gives that characteristic clean, minty note with a hint of camphor-like freshness. While camphor, menthol, and limonene each have distinct scents—camphor more medicinal, menthol with a cooling minty feel, and limonene a citrusy aroma—they don’t capture the specific eucalyptus smell as accurately as eucalyptol. So the compound most closely linked to that eucalyptus aroma is eucalyptol.
