Systematic Treatment of Equilibrium
Here we examine the equilibrium of calcium fluoride dissolving in water. First an ICE table is used to estimate the calcium concentration. Then systematic treatment of equilibrium is used with the Ksp, Ka, Kb, Kw, mass balance, and charge balance equations.

    so zaitsev major goes after the one with the lowest H's and forms the double bond to stabalize the molecule after the leaving group leaves. The strong base deprotonates the H and the h leaves its electrons behind where the double bond is formed and stabalizing the molecule.

  • @alexrobinson703
    @alexrobinson703 2 місяці тому

    I have a question. I've been taught to go from one side of the molecule to the other, but when you did the last example, you started from the functional group, to the end on each end. What is the reasoning? Is it because we've already identified it as an anhydride(carboxylic acid-water) and we are working from inside to outside in abc order? I've only done organic chemistry 1 and it was a while back.

    • @Chemistryuniversity
      @Chemistryuniversity 2 місяці тому

      We need a consistent starting point for numbering. Often that is from one side to the other to minimize the numbers. In many functional groups they will be on the end of a chain like carboxylic acids or aldehydes. In the case of anhydrides and esters the functional group will be in the middle so we work from there.

  • @SenseiMidas

    In the 2nd example, the reaction created charges, but why? Shouldn't it neutralize any charges. It isn't energetically favorable

    • @Chemistryuniversity
      @Chemistryuniversity 2 місяці тому

      In that case SN1 may be more likely, but SN2 can still happen. NH3 is a good attacker and the leaving group is very stable. This video is more about how to draw a SN2 mechanism, even if it is less likely.

    What do you mean by just the spectroscopy

    • @Chemistryuniversity
      @Chemistryuniversity 2 місяці тому

      Using vibrational spectroscopy (IR) the sulfur oxygen bond shows it is a double bond.

    Question: why doesn't the Br radical attack the double bond(like in anti markovnikov)? Also, cool pen 😮

    • @Chemistryuniversity
      @Chemistryuniversity 2 місяці тому

      The radical is resonance stabilized. If the concentration of either HBr or Br2 gets too high, then addition to the double bond will occur.

      Because, fundamentally, this isn't Chemistry. The labels "C", "D", etc. refer to different kinds of "Groups". They are mathematical structures that obey similar laws. This is just the application of a branch of Math called Group Theory to atoms and molecules. Group Theory can be used to describe the symmetry of any object, not just molecules. But, ultimately, what you need to know for Chemistry is the different symmetry operations. Flipping across a mirror plane, rotating a molecule, or doing a combination of both. Also, importantly, according to Group Theory there exists an "identity" operation, usually denoted by "e", which doesn't change the molecules orientation at all. Doing different combinations of symmetry operations will be equivalent to doing some other symmetry operation in the Group. For example, flipping an atom across a mirror plane through the middle of the molecule is the same as rotating 180°. Rotating 360° is the same as the identity operation "e", and so on.
