    Thanks for your efforts, I’ve disputed this video. Nothing to do with the content only the audio. I can’t hear anything over my background noises. This wasn’t a problem on the first few videos on this playlist (Sal was the teacher I believe), so please please fix the audio. Same for the next couple of videos in this playlist (Acid, bases and pH). I can’t follow them at all because of this 😩

  • Olivia Jones
    Olivia Jones 21 day ago

    For the molecule at 5:10, I thought coupling only occurs if they nuclei are 3 bonds or less apart? Does a double bond just count as 1 when you’re counting the bonds that separate them?

    • joelokoye23
      joelokoye23 14 days ago

      yeah, double bonds only count as 1 bond. What I don't understand though is at 1:08 he says that the n+1 rule only works for protons that are chemically equivalent (i.e. they in the same chemical environment and so have the same chemical shift). Isn't it the the other way round? Doesn't the n+1 rule work for chemically inequivalent protons?

    i apologize if im being stupid but why should we introduce H atoms on the benzene where as in the first question we draw another carbon next to carbonyl and add the hydrogen atoms there

    • Himani Rawat
      Himani Rawat Month ago

      what i infer from this is that we can't accommodate neighboring protons when it comes to benzene but still why has it got to be different

  • SydneyKay245
    SydneyKay245 Month ago

    Confused... In the last 3 videos, as the standard reduction potential value got bigger, the reducing agent strength got stronger and here that is reversed. Why?

    • SydneyKay245
      SydneyKay245 Month ago

      I see now. As the standard reduction potential value gets bigger, that reaction is more likely to be the reducing reaction, making it the better oxidizing agent. As the standard reduction value gets smaller, that reaction is more likely to be the oxidizing reaction, making it the better reduction agent.

    What does it mean "electrons falling to 3 to 2?

    • Nicole Lee
      Nicole Lee 2 months ago

      When electrons absorb enough energy, they will be excited from their ground state (n=2) to a higher energy level (n = 3). They won't stay in that state though because it's unstable. So the electron will release that energy it absorbed and fall back to it's ground state (n = 2). When it does that, the energy it released was in the form of light, which we see as red light.

  • Thành Cao

    The ‘N-1’ law doesn’t apply to the green proton in the first spectroscopy, because the next door protons are not equal. It is a bit more complicated than that.

  • DiseaseFN
    DiseaseFN 2 months ago

    The reason why the OH group can leave is because the reaction proceeds via an E1CB where CB means conjugate base. The protons on the alpha carbons ie the ones that are adjacent to the carbonyl are relatively acidic and so can be deprotonated by a weak base. This results in the enolate anion to form which is a relatively stable conjugate base. although this anion is stable it still prefers to lose an OH group ( Due thermodynamic stability reasons) and so the oxygen on the enolate ion collapses back which kicks of the adjacent double bond which then subsequently kicks off the OH group. Hope this helps.
