Assign E or Z to the alkenes shown below:
Understand the Problem
The question asks to assign the configuration (E or Z) to the given alkenes, which involves analyzing the substituents attached to the double-bonded carbons based on the Cahn-Ingold-Prelog priority rules.
Answer
Molecule a is E, molecule b is Z.
The final answer is: molecule a is E, molecule b is Z
Answer for screen readers
The final answer is: molecule a is E, molecule b is Z
More Information
The E/Z nomenclature system assigns priority to substituents around a double bond. If the higher-priority groups are on opposite sides, it’s E (entgegen); if on the same side, it’s Z (zusammen).
Tips
Common mistake is not following the Cahn-Ingold-Prelog priority rules carefully.
