(a)
To determine: The number of isoprene units in the given terpene and identification of the terpene as a monoterpene, sesquiterpene or diterpene.
Interpretation: The number of isoprene units in the given terpene and identification of the terpene as a monoterpene, sesquiterpene or diterpene are to be stated.
Concept introduction: An isoprene unit is bunched of five-carbon atoms. In terpenes, the isoprene units are connected to each other in head to tail fashion. The head part of an isoprene unit is branched, whereas the tail part of an isoprene unit is un-branched.
