(a)
Interpretation:
The given compound has to be assigned as E or Z configuration.
Concept Introduction:
Alkene:
The systematic name of alkenes are written by replacing “ane” of
E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the double bond.
Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the double bond.
(b)
Interpretation:
The given compound has to be assigned as E or Z configuration.
Concept Introduction:
Alkene: Unsaturated hydrocarbons having at least one double bond between two carbon atoms are known as alkenes.
The systematic name of alkenes are written by replacing “ane” of alkane with the suffix name “ene”. Numbering of the main chain should be in such away that alkene group must get lowest possible numbers.
E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the double bond.
Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the double bond.
