(a)
Interpretation:
The type of isomers in limonene has to be identified.
Concept Introduction:
Chiral carbon: A carbon is said to be chiral carbon if it is bonded to four different substituents.
Chirality: It refers to a Carbon atom in a molecule that contains four different substituents.
Enantiomers: They are chiral molecules whose mirror images are not superimposable.
(b)
Interpretation:
Possibility of having E, Z isomers in limonene has to be identified.
Concept Introduction:
Geometric isomers: Two compounds are considered as geometric isomers of each other if both contain same number of atoms but different in their arrangement.
E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the double bond.
Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the double bond.
(c)
Interpretation:
Reason for why isomers of limonene smell differently has to be explained.
