Distinguishing the difference between E/Z configuration

Click For Summary

Discussion Overview

The discussion revolves around the identification of E/Z configurations in a chemical structure, specifically in the context of a homework problem. Participants are exploring the criteria for determining these configurations based on substituent arrangements around a double bond.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant has narrowed down possible answers to A, B, or C but is uncertain about the E/Z configuration.
  • Another participant questions the reasoning behind considering E or Z configurations, prompting further exploration of the criteria.
  • A third participant suggests that the presence of a double bond may allow for E/Z consideration.
  • Concerns are raised about the implications of having identical substituents on the same sp2 carbon, indicating a need to review E/Z nomenclature rules.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are differing views on the applicability of E/Z nomenclature based on the specific structural features discussed.

Contextual Notes

The discussion highlights potential limitations in understanding the rules of priority for E/Z nomenclature, particularly in cases with identical substituents, which may affect the determination of configuration.

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.
