Concept explainers
(a)
Interpretation:
The configuration (E-Z) of the given compound has to be assigned.
Concept introduction:
E-Z designators are used as like cis-trans terminology for non-similar groups attached
In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher atomic weight of connected atom, if it is same for the connected atom then consider the next atom of each group and so on. In case of multiple bonds connected with same atoms, then the higher bonds having group has higher priority.
If the higher priority groups are on the same sides, then the configuration is designated as Z. If the higher priority groups are on the opposite sides, then the configuration is designated as E.
(b)
Interpretation:
The configuration (E-Z) of the given compound has to be assigned.
Concept introduction:
E-Z designators are used as like cis-trans terminology for non-similar groups attached alkenes.
In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher atomic weight of connected atom, if it is same for the connected atom then consider the next atom of each group and so on. In case of multiple bonds connected with same atoms, then the higher bonds having group has higher priority.
If the higher priority groups are on the same sides, then the configuration is designated as Z. If the higher priority groups are on the opposite sides, then the configuration is designated as E.
