| 3-carene | | car-3-ene |
| 4-cymene | A monoterpene that is toluene substituted by an isopropyl group at position 4. | p-cymene |
| alpha-terpinene | One of three isomeric monoterpenes differing in the positions of their two double bonds (beta- and gamma-terpinene being the others). In alpha-terpinene the double bonds are at the 1- and 3-positions of the p-menthane skeleton. | alpha-terpinene |
| camphane | | bornane |
| camphene | A monoterpene with a bicyclic skeleton that is bicyclo[2.2.1]heptane substituted by geminal methyl groups at position 2 and a methylidene group at position 3. It is a widespread natural product found in many essential oils. | camphene |
| carane | A carbobicyclic compound that is bicyclo[4.1.0]heptane substituted by methyl groups at positions 3, 7 and 7. | carane |
| gamma-terpinene | One of three isomeric monoterpenes differing in the positions of their two double bonds (alpha- and beta-terpinene being the others). In gamma-terpinene the double bonds are at the 1- and 4-positions of the p-menthane skeleton. | gamma-terpinene |
| myrcene | A monoterpene that is octa-1,6-diene bearing methylene and methyl substituents at positions 3 and 7 respectively. | beta-myrcene |
| pinane | A monoterpene that is bicyclo[3.1.1]heptane substituted by methyl groups at positions 2, 6 and 6. | pinane |
