    Very clear video. Only problem is the pka table. Our prof doesn't allow a pka table, explaining to me we should "know the trends of acids and bases" this is extremely frusterating when it comes to nucleophilicity and leaving groups as they are correlated with basicity.

    in the pka table water is shown as a poor leaving group, but right after it's shown as an example of a good leaving group (?) so which one is it then?

      h2o is made from stronger acid h3o+ hence a better leaving group
      oH- is mad from h2o which is weak acid and hence weak leaving group

  • @harrisoncollege101

    can someone please tell me whether the tosylate or chloride ion is the better leaving group please?

    • @MasterOrganicChem
      @MasterOrganicChem  10 ปีที่แล้ว +6

      Tosylate is actually a better leaving group than chloride.

    Thanks so much for the videos!!! I have an exam tomorrow,
    how do I determine which leaving group will make the fastest reaction if Im given a few options?
    The strongest acid will also make the reaction be the fastest?

    • @AS_974
      @AS_974 ปีที่แล้ว

      If the conjugate acid of a leaving group has a low pka value, it will make a good leaving group.

  • @adosar7261
    @adosar7261 5 ปีที่แล้ว

    A good leaving group is one that decreases the free energy of the products. A good nucleophile is one that increases the free energy of the reactants. So how it is possible iodine ion to be a both good nucleophile and leaving group? Thanks in advance.

    but why are weak bases better leaving groups?

    • @nizzle1931
      @nizzle1931 6 ปีที่แล้ว +2

      He said that weak bases are fairly stable even when they are not attached to another atom/molecule. A strong base is not stable by itself and so will not separate from an atom/molecule easily.

      @@strongbodystrongmiind Yeah, it did. Strong bases are not stable by themselves, so they will not easily separate from an atom/molecule (they will not LEAVE easily). Weak bases are fairly stable by themselves when not attached to another atom/molecule (in comparison to a strong base, they can LEAVE easily, hence a good leaving group).

    I thought as we go down the periodic table the nucleophilicty of our species increases, so why is iodide and cl- good leaving groups eve know they are strong bases?

      the nucleophilicity of halogens actually varies with change in the solvent they are kept in
