    Correction: At 1:24:15 the faces are enantiotopic in first example since one asymmetric center is generated,here, after nucleophilic addition reaction on the carbonyl face.

      Almost every example about topicity of faces is wrong

    Identical k liye bs superimposable hona jaruri hai. Mirror image h ya nhi farak nhi pdta.
    Step 1: Check if superimposable or not
    -If yes= identical
    -if no (move to step-2)
    Step-II: Check if mirror images or not
    -if yes= enantiomers
    -if no= diastereomers
    Please correct me if I'm wrong???

    1=Diastereotopic
    2=Diastereotopic
    3=Homotopic
    4=Diastereotopic
    Please verify these 4 examples and trim out this section from the video.

    Sir 27:24 p.. 3 membered ring m nd 4 member ring m third carbon tk environment same h to 4 member wali ring m atomic weight jyda h to priority 4 member ring ko q nii mili??? Agr dono ring m oxygen side se dekhna start krte h to...

    • @sachinzambre5050
      @sachinzambre5050 2 года назад +2

      Because if you seen,if you compare between 3 and 4 membered rings, carbon 1 is attached directly to oxygen in both so skip it but if you see carbon 2 ........in 3 membered ring it is attached directly to oxygen but in 4 membered ring it is attached to another carbon.so we give priority to small ring according to nature if carbon 2

    1st example of identifying face- It should be enantiotopic...right?

    • @sachinzambre5050
      @sachinzambre5050 2 года назад

      Yes! You are right .it should be enantiotopic. It's correction. Thanks for notifying

    Correction regarding topcity of faces of bicyclo[2.1.1]hexan-2-one. This compound has enantiopic faces, because after attack on either side we are getting Ena timers NOT homotopic.

  • @neerajbhatt2185
    @neerajbhatt2185 2 года назад

    In 1st example of topicity in faces... we rotate the molecule so why did we not rotate the molecule of 2nd example after substitution when we are checking topicity

    Sir , d and l is also configuration it does not related with optical activity .🤔i think u say wrong about d and l notion.

    • @sachinzambre5050
      @sachinzambre5050 2 года назад +3

      Small d and Small l not related with configuration. The only indicate either light is rotated dextro or leavo
      .
      Capital D and capital L are related with configuration in fisher form for carbohydrates.
