Distinguishing the difference between E/Z configuration

AI Thread Summary
The discussion focuses on distinguishing between E and Z configurations in molecules with double bonds. Participants emphasize the importance of identifying substituents and applying priority rules for E/Z nomenclature. The presence of identical substituents on sp2 carbons complicates the determination of configuration. Clarification is sought on how identical groups affect E/Z classification. Understanding these concepts is crucial for accurately determining molecular geometry.

Homework Statement



Ive narrowed the question down into A,B,C as the possible answers, but I can't determine if it is E,Z or neither configured. Any help would be great.

Why would you think it should be either E or Z?

I thought it would be possible because of that double bond.
 
But what happens when there are two identical substituents attached to the same sp2 carbon? Review the rules of priority for E/Z nomenclature.
