Q: An important bicyclic terpene is:
  • A. Limonene
  • B. Pinene
  • C. Cymene
  • D. Myrecene
Correct Answer: Option B - Pinene (C₁₀ H₁₆) is a bicyclic, double bond, terpenoid hydrocarbon representing the family of monoterpenes. Some other examples of bicyclic monoterpenes include carene, sabinene, camphene, and thujene. It found in the essential oils of many plants, particularly conifers like pine trees. It exists in two isomeric forms-alpha pinene and beta pinene.
