Distinguishing the difference between E/Z configuration

Click For Summary
SUMMARY

The discussion focuses on distinguishing between E and Z configurations in organic chemistry, particularly concerning double bonds and substituents. Participants emphasize the importance of understanding the priority rules for E/Z nomenclature, especially when identical substituents are present on sp2 carbons. The consensus is that the presence of identical substituents complicates the determination of E/Z configuration, necessitating a thorough review of the established nomenclature rules.

PREREQUISITES
  • Understanding of E/Z nomenclature rules in organic chemistry
  • Familiarity with sp2 hybridization and double bonds
  • Knowledge of substituent priority in chemical structures
  • Basic concepts of stereochemistry
NEXT STEPS
  • Review the Cahn-Ingold-Prelog priority rules for E/Z configuration
  • Study examples of E/Z isomerism with identical substituents
  • Learn about stereochemical representations in organic compounds
  • Explore the implications of E/Z configurations in chemical reactivity
USEFUL FOR

Chemistry students, organic chemists, and educators seeking to deepen their understanding of stereochemistry and E/Z nomenclature.

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.
