    Great video explaining these reactions! My professor tends to lose me by going into too much detail and forgetting that we are not all professionals in OCHEM. This video gives me exactly what I need to know about each reaction in a simplified manner! Thank you!

      So many professors forget that the reason they have students is that it is their job to teach chemistry to those who don't yet know it! I'm glad my videos are able to fill in where your professor is unable to

    You are the best. I'm on the chapter of Reactions to Alkenes and it's a huge chapter to read. We have the powerpoint slides but the professor just goes through each slide which makes it hard to understand. Your video pretty much summed up most reactions that we reviewed in class. But now, I have a better understanding.

    Im not sure if you realized but you contradicted yourself for the halohydrin. you mentioned that the halogen goes to the less substituted (markovnikov because more H bonds) but then you said that this is a markovnikov reaction because the solvent without the H adds to the more substituted carbon which is the opposite of markovnikov.

    • @Leah4sci
      @Leah4sci  3 ปีที่แล้ว

      Thanks for watching and for your comment! I do not believe I contradicted myself. Halohydrin formation is a Markovnikov reaction because the nucleophile (in this case, the polar protic solvent) adds to the more substituted carbon. It is the solvent, not the halogen, that adds last in the reaction mechanism. For the complete breakdown of the reaction mechanism, visit leah4sci.com/halohydrin-formation/

      I was thinking the same thing. I expected a hydride shift

    • @OPT15
      @OPT15 5 ปีที่แล้ว +1

      In this case there is no carbocation intermediate. The nucleophile (H2O) attacks the delta positive carbon on the bromonium. Because there's no true carbocation, no rearrangement

    • @Leah4sci
      @Leah4sci  9 หลายเดือนก่อน

      There's no 'free' carbocation in this reaction. Instead it's a partially positive carbon held in place by the bromonium. OH is attracted to the partially positive carbon and IN attacking, breaks the carbon-bromine bond. Without a free carbocation there is no shift

  • @hannahpederson3445
    @hannahpederson3445 ปีที่แล้ว

    Hi! I was wondering why there is a hydride shift in the hydrohalogenation, but not any of the others shown given that true same alkene is being used in each mechanism. Doesn’t each alkene reaction exhibit a carbocation intermediate, and if so, why do the other examples not go through a hydride shift?

    Hey Leah. I'm REALLY into chemistry and I've gotten myself some equipment (the basic lab stuff: beakers, hotplate stirrer, water bath, sep. funnel, büchner funnel, distillation apparatus, etc.)
    I know basic chemistry - but I really, really wanna get into more advanced stuff like organic chemistry.
    I've watched your videos on naming things, and I can do that now. That is great and all, but no real use if I can't come up with a way to synthesize the molecules that I'm naming.
    What do you suggest as a good starting base for organic chemistry? I reckon your videos start at atleast intermediate level.

      ​@@Leah4sci Hey Leah, what a reunion 8 years later. I now have a degree in pharmacy (first 3 semesters are organic chemistry), a quite elaborate home laboratory, and have various optimized syntheses processes based on patents. I remember watching this video 8 years ago when I was just 16 years old, and without many resources, so glassware and even basic chemicals were super exciting. Funny how life progresses.
      I truly admire your initiative at the time (and perhaps ongoing?) to teach the youth about organic chemistry and nourish the young minds with the intrigue of the complex nature of these chemical groups and the exciting reactions we have devised to add or subtract them to bend the molecules to our will.
      Merry Christmas, and thanks again!

      A syn addition would be when two substituents are added to the same side or face of the double bond. The opposite of this would be anti addition, where substituents are added to opposing sides or faces of the double bond.

    How do I know if a reaction will do an anti markovnikov addition or a markovinkov addition? Is it just purely memorizing which reaction does what or is there some trick

    • @Leah4sci
      @Leah4sci  3 ปีที่แล้ว

      To understand why any given reaction produces a Markovnikov or anti-Markovnikov product, you must understand something about the reaction mechanism itself. Determining the favored product of the reaction is really all about identifying the reaction intermediate. In short, Markovnikov reactions usually have highly stable carbocation intermediates, while anti-Markovnikov reactions do not show a carbocation intermediate. For more on this, visit my tutorial at leah4sci.com/markovnikov

    My textbook (Wade) says that Oxymercuration-Demurcation/Alko... has no stereochemistry, so there's no Anti/Syn

    • @Leah4sci
      @Leah4sci  3 ปีที่แล้ว

      From a stereochemical perspective, oxymercuration is an anti addition. This has to do with the formation of the mercurinium ion as an intermediate. The nucleophile cannot attack from the same side as the mercury because of steric hindrance. If you’d like to further break down any statements from your textbook, I’d love to do so in my Organic Chemistry Study Hall. For more information, go to studyhall.leah4sci.com/join

    How do you know when a carbocation will form?

    • @Leah4sci
      @Leah4sci  9 หลายเดือนก่อน

      If the pi bond reaches out to attack another atom, it only attaches to ONE of the 2 sp2 carbon atoms. The other will be a carbocation as a result of being abandoned by the bond

    • @Leah4sci
      @Leah4sci  3 ปีที่แล้ว

      Glad I helped clear things up for you. Regarding your questions, a hydride shift can occur in organic chemistry reactions that involve a carbocation intermediate. If such a rearrangement will place the carbocation on a more substituted carbon, then the hydride shift is highly favorable because of its ability to stabilize the intermediate. For more, visit leah4sci.com/hydride-shift-mechanism/

      Yes, those are also acceptable reagents for the cyclopropanation of an alkene.

  • @baldski8866
    @baldski8866 2 ปีที่แล้ว

    Very good but only one question.... In the hydrohalogenation example, isn't the Cl going to go on the C that has the less H, being a Markovnikov reaction? Why does the Cl go on a C that has no pi bonds?

    • @Leah4sci
      @Leah4sci  2 ปีที่แล้ว

      Listen to my explanation in the video one more time. For this example, there is a hydride shift that allows the carbocation to be formed on the more substituted, tertiary carbon. For more on the mechanism of a hydride shift like this one, I invite you to watch the following: th-cam.com/video/cSW9LDxtuoA/w-d-xo.html

      Think of this video as a short summary of all of the other alkene reactions presented in the series. As such, I would watch this video either first (as a preview of what’s to come) or watch it last (as a quick review of everything). For the entire series, in correct order, visit my website at leah4sci.com/alkene-reactions

  • @pmat2757
    @pmat2757 2 ปีที่แล้ว

    In the halohydrogenation 4:32 would there be a carbocation shift towards the tertiary carbon so that OH would be on the more carbon

    • @Leah4sci
      @Leah4sci  2 ปีที่แล้ว

      Actually, no. The formation of the halonium ion intermediate prevents the possibility of a carbocation rearrangement. For more on this reaction, watch my video at th-cam.com/video/S-2CaHDhMfI/w-d-xo.html

    Why do these have catalysts, like a Pd, that doesn't seem to react with anything. Mechanisms are the only aspects I'm stuck on before the finals. Also curious as to why it's in Hydrogenation but not Hydrohalogenation.
