(a)
Interpretation:
Isoprene units in the given set of compounds need to be circled.
Concept introduction:
Terpenes are naturally occurring compounds which share a common feature. All terpenes are thought to be assembled from isoprene units having five carbon atoms. So the structure of terpenes has the carbon atoms in multiples of five only.
The isoprene units are identified by following few steps namely,
- Identify the number of isoprene units
- Look for methyl group
- Trial and error to find isoprene unit
To identify: the isoprene units in bisabolene

- Problem 3-42 Consider 2-methylbutane (isopentane). Sighting along the C2-C3 bond: (a) Draw a Newman projection of the most stable conformation. (b) Draw a Newman projection of the least stable conformation. Problem 3-44 Construct a qualitative potential-energy diagram for rotation about the C-C bond of 1,2-dibromoethane. Which conformation would you expect to be most stable? Label the anti and gauche conformations of 1,2- dibromoethane. Problem 3-45 Which conformation of 1,2-dibromoethane (Problem 3-44) would you expect to have the largest dipole moment? The observed dipole moment of 1,2-dibromoethane is µ = 1.0 D.
