Question
Chapter 5, Problem 5.30P
(a)
Interpretation Introduction
Interpretation:
Structural formula of lycopene has to be drawn showing the two sets of four isoprene units linked to form lycopene.
Concept Introduction:
Terpenes are made by joining five-carbon units, usually in a head to tail-fashion.
Isoprene unit:
Branched end of isoprene – Head
Unbranched end of isoprene - Tail
(b)
Interpretation Introduction
Interpretation:
Number of double in lycopene that has a possibility of cis, trans isomerism has to be given and the double bond that shows cis and that shows trans isomers has to be identified.
Concept Introduction:
Terpenes are made by joining five-carbon units, usually in a head to tail-fashion.
Isoprene unit:
Branched end of isoprene – Head
Unbranched end of isoprene - Tail
Alkene:
- • Trans configuration: In trans configuration, carbon atoms present in the main chain are placed on opposite sides of the carbon-carbon double bond.
- • Cis configuration: In cis configuration, carbon atoms present in the main chain are placed on same sides of the carbon-carbon double bond.
