Concept explainers
(a)
Interpretation:
E or Z configuration has to be identified for the given compounds.
Concept introduction:
Cis–trans isomerism (or) geometric isomerism or configurational isomerism:
The two similar groups (or higher priority groups) are in same side in double bond of
Example:
(b)
Interpretation:
E or Z configuration has to be identified for the given compounds.
Concept introduction:
Cis–trans isomerism (or) geometric isomerism or configurational isomerism:
The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z-isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E-isomer).
Example:
(c)
Interpretation:
E or Z configuration has to be identified for the given compounds.
