(a)
Interpretation:
The given reaction is
Both compounds has to be showed as terpenes.
Concept Introduction:
Terpene:
The compounds which contains two or more isoprene units in their structure are said to be terpenes.
Isoprene (2-methyl-1,3-butadiene) unit is a molecule with five carbon atoms with double bonds.
(b)
Interpretation:
A mechanism for the conversion of (S)-Citronellal to Isopulegol has to be proposed.
(c)
Interpretation:
In Isopulegol, the number of stereocenters present has to be given and the number of stereoisomers possible for a molecule with this number of stereocenters has to be given.
Concept Introduction:
A carbon which is bonded to four different groups is said to be chiral carbon. A chiral carbon in a molecule is said to be chiral center. All chiral centers are stereocenters.
(d)
Interpretation:
Isopulegol is formed as a single stereoisomer. The fact that only single stereoisomer is formed has to be accounted.
