Terpenes are classified by the number of carbons: monoterpenes (C 10), sesquiterpenes (C 15), diterpenes (C 20), as examples. The terpene alpha-pinene is a major component of the common solvent, turpentine. The one terpene that has major applications is natural rubber (i.e., polyisoprene).
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C 10 H 16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids ...
A terpene is a naturally occurring hydrocarbon based on combinations of the isoprene unit. Terpenoids are compounds related to terpenes, which may include some oxygen functionality or some rearrangement, however the two terms are often used interchangeably.

Diterpenes are a class of terpenes composed of four isoprene units, often with the molecular formula C 20 H 32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway , with geranylgeranyl pyrophosphate being a primary intermediate.
D-Limonene, a terpene. Solvents in a diverse class of natural substances called terpenes are obtained by extraction from certain parts of plants. All terpenes are structurally presented as multiples of isoprene with the gross formula (C 5 H 8) n. D-limonene, a monoterpene, is one of the best known solvents in this class, as is turpentine.
Terpenoids are modified terpenes, [7] wherein methyl groups have been moved or removed, or oxygen atoms added. Some authors use the term "terpene" more broadly, to include the terpenoids. Just like terpenes, the terpenoids can be classified according to the number of isoprene units that comprise the parent terpene:
