E/Z Absolute Configuration of Alkenes



It’s EZ to assign E and Z absolute configuration to alkenes. Guess which convention we get to use? Cahn-Ingold-Prelog is back! Don’t forget, zee zame zide. You have to say it with a German accent, or you lose points on the quiz.

  1. you know these are all bangers and under watched. no adds!!???? thank you so much Professor Dave. I watched this to get through ochem when they came out. now I am studying again, these videos are more perfectly made than I had realized before. exactly what you need to know in the shortest possible time

  2. I already searched it up before 'cause in your previous video about Zaitsev and Hofmann, when you were talking about alkene with substituents in descending order you talked about E/Z disubstituted and I didn't know what that meant.

  3. i have my first orgo test tomorrow and i sadly forgot that i was registered for the class until 3 days ago so these videos are helping me get a general understanding of what will be on my test. Im not expecting the greatest grade on this exam, but the way you explain the content is very helpful.

  4. Great explanation, but if z means zee zame zide … why didn’t chemists just keep using cis/trans? Either way the cahn-ingold rules for priority would be needed to clear up ambiguity
