(a) The sex attractant of the Mediterranean fruit fly is (E)-6-nonen-1-ol. Write a structural formula or build a molecular model for this compound, showing the stereochemistry of the double bond.
(b) Geraniol is a naturally occurring substance present in the fragrant oil of many plants.
It has a pleasing, roselike odor. Geraniol is the E isomer of (CH3)2C = CHCH2CH2C = CHCH2OH
CH3 Write a structural formula or build a molecular model for geraniol, showing its stereochemistry.
(c) Nerol is a naturally occurring substance that is a stereoisomer of geraniol. Write its structure or build a molecular model.
(d) The sex attractant of the codling moth is the 2Z, 6E stereoisomer of (CH3)2CCH2C = CHCH2CH2C = CHCH2OH
CH3
CH2CH3
Write the structure of this substance or build a molecular model in a way that clearly shows its stereochemistry. (e) The sex pheromone of the honeybee is the E stereoisomer of the compound shown. Write a structural formula or build a molecular model for this compound. CH3C (CH2)4CH2CH = CHCO2H
(f) A growth hormone from the cecropia moth has the structure shown. Express the stereochemistry of the double bonds according to the E–Z system.
