There are many more videos related to different topics like stereochemistry, pericyclic reactions, name reactions, coordination chemistry. I have organized them in different folders in playlist of my channel. If you are interested in those topics you can go through them.

    For the example at 14:58, I don't get why there are only 3 C2, why do you only cut between H1 and H2, H3 and H4, why not also between H2 and H3, H3 and H4, and H2 and H4.

    • @rithik3871
      @rithik3871 2 года назад

      Cause when you cut through the other bonds you automatically cut through the alternative bonds too
      For example H1 and H2 bond cuts through H3 and H4 bond
      I hope it helps

    • @Maryam_Khalid_g6i
      @Maryam_Khalid_g6i 3 месяца назад

      On the basis of after how much rotation it gains the original orientation
      For C2 = 360/2= 180
      After 2 rotation of 180
      It comes to original shape

    • @niveoIe
      @niveoIe 4 года назад

      in order to obtain the an orientation indistinguishable from the original upon rotation, the bottom two H that are on the same plane must be rotated by 180 in order to stay on the plane.

    Sir
    Most humbly and respectfully I have to State that I have some problems in group theory
    1) what is reducible representation of cis butadiene
    2) what is reducible representation of Trans butadiene
    Kindly sir help me immediately on my email.

    • @ChemWis
      @ChemWis  4 года назад +1

      I am giving you the hint. The irreducible representation for all the molecules belonging to a particular point group remains the same. Cis-butadiene belongs to C2V point group (which is the point group of water) and trans-butadiene belongs to C2h (which is the point group of trans -1,2-dichloroethylene). So, the irreducible representation of cis-butadiene will be the irreducible representation of water and irreducible representation of trans-butadiene will be the irreducible representation of trans -1,2-dichloroethylene or any molecule belonging to C2h point group.
