    At 5:56 Why it is not like that: bromine is on the left side of the top of the structure, if it is mirror immage, it should be like I said?

    • @strawberryskates
      @strawberryskates 4 роки тому +1

      So in this case, its kind of like imagining that the mirror is in front of the molecule. The Bromine which was on a wedge i.e. in front of the plane would appear to be behind the plane in the mirror. Hence why it is on a dash and is not on the left side of the molecule.

    • @adansilva6851
      @adansilva6851 3 роки тому +1

      also because stereoisomers have same connectivity so if the bromine is on the second carbon, then in the other enantiomer it must stay on the second carbon (pretty sure this is correct info)

    • @rwayle
      @rwayle 3 роки тому

      You can’t have 4 enantiomers by definition, only ever 1.
      SS would be the enantiomer of RR, SR would be the enantiomer of RS. One of these pairs may be meso, depends on the compound.

  • @andrewjustin256
    @andrewjustin256 Рік тому +1

    1:11 Aren't they meso compounds? I don't believe they are enantiomers, because if we assume there is a mirror in front of the compound on the left, it should have a mirrored image, implying the chiral chain that is on the backwards now should be on the front and vise versa, while those who are neither front or back should be the way they are.

    • @paysonkeown2960
      @paysonkeown2960 9 місяців тому

      These are not meso compounds. The mirror plane identification for meso compounds has to put the plane within the molecule. There are no planes of symmetry in the molecule.

    • @heavenkleinschmidt6340
      @heavenkleinschmidt6340 2 місяці тому +1

      Wedge just means it's facing toward you on the page of the plane. The priority is all about the atomic number or Proton number of thr atom. Br has a higher atomic number than say methyl or hydrogen so it's more of a priority

      @w07106123 4 роки тому +8

      @@serena_bee No that is not correct. RS configurations have nothing to do with + or - molecules. The only way to determine whether the molecule is + or - is to put the molecule sample into a polarimeter to measure which way the plane polarised light rotates. RS configurations is just a way to express what kind of enantiomer you're referring to so that others know what you're talking about without measuring the optical activity of the molecule.

    • @w07106123
      @w07106123 4 роки тому +3

      I would say there is no easy way to distinguish between enantiomers of 2-amino butane. The only way I could think of is to measure their optical activities in a polarimeter but this only works if you have two separate samples of the enantiomers. It doesn't work if you have a racemic mixture.

    • @tolulopedurosinmi5630
      @tolulopedurosinmi5630 4 роки тому +2

      You reverse it because you want the CH3 (or whatever is higher than H) on the dashed block to go on the wedge and then you swap the configuration since you're taking H to the back.

    • @laurenmcgavin7858
      @laurenmcgavin7858 4 роки тому +6

      There are two steps to assigning configurations to stereogenic centres:
      step 1: assign priority based on the atomic number of the attached atoms (e.g. Bromine is labelled as priority one at 1:30 and hydrogen is priority 4)
      step 2: orientate the molecule so that the lowest priority atom (usually hydrogen) is at the back, furthest away from the viewer (this position is represented by the dashed bond)

      It’s not because for a tetrahedral carbon to be a chiral center it has to have 4 different substituents. The carbon in the methyl group is bonded to 3 hydrogen atoms, which are not different, therefore it is not chiral
