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.

Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died.
Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom? In considering contributing structures to each hybrid, do not consider structures in which more than one atom has an incomplete octet
