Here's the PDF by request: tinyurl.com/yunjj4ty Just a note - in this video I do not make a distinction between SN2 and E2 as which is major or minor. You may need to follow a guideline in your own classes, such as when you have a secondary or tertiary leaving group, E2 is favored (major), while with primary leaving groups, SN2 is favored. This is due to not only steric hindrance as an issue fo...

    Good evening Doc I'm from South Africa ,Great channel. Which workbook do you use for org chem undergraduate lessons? Ill be assisting with teaching this year so I'm just trying to find multiple sources to assist first-year students as organic chemistry appears to be a major challenge. I have the Klein 5th edition and organic chemistry as a second language by Klein. If you could assist in this regard I would appreciate it.

    • @orgotime6196
      @orgotime6196 2 года назад

      The key is understanding the reagent on top of the arrow. It’s a good Nu so it favors SN2 over SN1, and it’s a strong base which favors E2 over E1. Because it’s a secondary alkyl halide, both are possible. The chart on this page from Klein might help you with knowing whether the reagent is a strong or weak Nu and strong or weak base: www.bartleby.com/solution-answer/chapter-1010-problem-1027p-organic-chemistry-as-a-second-language-first-semester-topics-4th-edition/9781119110668/cd1360b4-5079-11e9-8385-02ee952b546e

    Great video, thanks for the clear and effective examples. On the worksheet linked in the description, why do examples f and h favor E2 over SN2? I thought due to NaOH being a small and strong base they would favor SN2, is it because they are too sterically hindered to do SN2 effectively?

    • @orgotime6196
      @orgotime6196 2 года назад

      Yes- when both SN2 and E2 are possible, secondary and tertiary alkyl halides favor E2 because of less sterics but also the stability of alkene being formed, over primary halide being favored for SN2

      Actually E2 is favored in protic solvent- that is a big difference between E2 and SN2. Further reference about this: www.masterorganicchemistry.com/2012/12/04/deciding-sn1sn2e1e2-the-solvent/

    how do you know what will qualify as steric hindrance? what if the attraction energy of the attacking molecule is high enough to overcome it (bend the bonds of the existing geometry of the attacked molecule)? this shit is why organic chemistry is 90% hand-waving garbage.

    • @orgotime6196
      @orgotime6196 2 года назад

      Hi Rick - we can get quantitative if you want, but most of the organic chem at this level is presented qualitatively to keep it accessible (I think). We try to recognize patterns from the data but I agree that omitting these data lead to feelings of hand-wavyness... Yes - I can understand your point. In general, what qualifies as enough steric hindrance to predict "no reaction" is going to be where the nucleophilic carbon is tertiary (and in some cases, secondary, or next to a tertiary carbon). I usually see 99.9% examples where something considered "branched" (isopropyl, isobutyl, or in a cyclic ring like DBN) to be hindered enough to predict no reaction or at best, minor products. We could get into the weeds on this and look up research articles siting repulsion energies if you'd like, but most treatments of this material remain qualitative. Advanced organic chem texts will go more into more detail.
