Question: Draw the structure corresponding to each IUPAC name.
Determine the parent carbon chain from the parent name and assign groups as per the numbering.
Alkenes are numbered such that the double bonds get the lowest values, followed by the groups attached.
The alkyl groups are placed around the C=C bonds as per E and Z names.
a. The parent name “hept” indicates that the parent chain consists of seven carbon atoms. The Z isomer has the higher priority groups on the same side of C=C.
Structure of a
b. The parent name “oct” indicates that the parent chain consists of eight carbon atoms. The E isomer has higher priority groups on the opposite sides of C=C.
Structure of b
c. The parent name “hex” indicates that the parent chain consists of six carbon atoms. The Z isomer has higher priority groups on the same side of C=C.
Structure of c
Question: Draw the structure of (2Z,6E)-3-ethyl-7-methyldeca-2,6-dien-1-ol, the sex pheromone of the codling moth, a common agricultural pest that destroys apple crops. By spraying an apple orchard with this pheromone, the mating of male and female moths is disrupted, and moth populations can be controlled.
