(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

- The statements in the tables below are about two different chemical equilibria. The symbols have their usual meaning, for example AG stands for the standard Gibbs free energy of reaction and K stands for the equilibrium constant. In each table, there may be one statement that is faise because it contradicts the other three statements. If you find a false statement, check the box next to t Otherwise, check the "no false statements" box under the table. statement false? AG"1 no false statements: statement false?

- What would happen if the carboxylic acid and alcohol groups were on the same molecule? In essence, the molecule reacts with itself. Draw the structure of the products formed in this manner using the reactants below. If two functional groups interact with one another on the same molecule, this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more) attack.
