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.

Compound A (C11H23Br) is a secondary alkyl halide. On being heated with a solution of sodium ethoxide in ethanol, compound A yielded a mixture of two alkenes B and C, each having molecular formula C11H22. Catalytic hydrogenation of the major isomer B or the minor isomer C gave only 3,5-diethylheptane.
Draw structures for compounds A, B, and C consistent with these observations.
Compound A(C7H15Br) is not a primary alkyl bromide. It yields a single alkene(compound B) on being heated with sodium ethoxide in ethanol. Hydrogenation of compound B yields 2,4-dimethylpentane. Identify compounds A and B.
Three constitutional isomers of molecular formula C 5H 8O can be converted to 1-pentanol (CH 3CH 2CH 2CH 2CH 2OH) on treatment with two equivalents of H 2 in the presence of a Pd catalyst. Draw the structures of the three possible compounds, all of which contain a carbonyl group
