Which statement about Artemisinin is correct?

Which statement about Artemisinin is correct?

• A. Artemisinin is a sesquiterpene.
• B. Artemisinin is a monoterpene.
• C. Artemisinin is a diterpene.
• D. Artemisinin is a tetraterpene.

Answer: (A)

Terpene class is determined by how many isoprene units make up the molecule. Artemisinin has three isoprene units, giving it 15 carbons in total, which classifies it as a sesquiterpene. Monoterpenes have 10 carbons (two isoprene units), diterpenes have 20 (four units), and tetraterpenes have 40 (eight units). So the statement reflecting Artemisinin as a sesquiterpene matches its carbon count and structure, making it the correct description.
