    Steric number is the number of atoms bonded to a central atom of a molecule plus the number of lone pairs attached to the central atom, not the number of sigma bonds. Acetylene has 3 sigma bonds and you only counted 2 which got me confused. I'm assuming in acetylene's case the 2 carbon atoms are considered as the "central atom"?

    • @lizvogel8227
      @lizvogel8227 4 года назад +6

      You are counting the number of sigma bonds around an atom eg, the carbon on the left. The steric number does not belong to the molecule, but instead belongs to a specific atom in the molecule - the carbon. There are 2 sigma bonds and no electron pairs on the individual carbón so it has a steric number of 2

    The primary cause of the shortening of the carbon-carbon bond is because of the pi bonds, not necessarily the increased s character -- even though that is a part of it, and is the reason that the carbon-hydrogen bonds will be shorter as well. If the primary cause was the increased s character, the carbon-oxygen bonds in CO2 would have near equivalent bond length as the triple bond, but they do not. I just wanted to mention that in the comments bc I was slightly thrown off when I heard that. Great video!

      Single bonds are sp3, sp2 are 2 single and 1 double, sp is 1 single and a triple or two double.

    I don't get how you get two SP hybridised orbitals. When you combine 2 orbitals that should make 1 new combined orbital. How do you get 2 ?

    Can anyone tell me why the pi bonds prevent rotation?

    • @Bailliemariee
      @Bailliemariee 4 года назад +3

      Hey there! The pi bonds prevent rotation due to the electron overlap above and below the plane of the atom! The molecule wouldn't be able to rotate freely around that axis due the two overlaps. I personally think about it as giving the atom more "structure". Hope that helped!

    • @lsrimathi7705
      @lsrimathi7705 6 лет назад

      Rotation is possible for sigma bonds. Pi bonds cannot be rotated as they will have to be broken first since they are formed only in addition to sigma bonds.

  • @straightupBall3r
    @straightupBall3r 9 лет назад +1

    Hey Jay, I have a question about the formation of 2 equal sp-hybrid orbitals that are opposite in orientation. How is this even possible since the formation of an sp-hybrid consists of an s-orbital of singular phase and a p-orbital of 2 opposing phases. Wouldn't one side of the sp-hybrids have a much larger electron density than the other side as that is the side that constructively interferes with the s-orbital? So how then do 2 sp-hybrids form that have equal and opposite electron densities? Thanks.

    • @MiamiCubanbcn
      @MiamiCubanbcn 8 лет назад +4

      I struggled with this too, but i then realized that the demotion of a p orbital carried its single electron and the s orbital also remained with its single electron. So, in reality you have 2 sp orbitals with a single electron occupying both. The linear orientation comes from the repulsion stemming from the single electrons occupying the remaining 2p orbitals and the pie bonds they create to prevent rotation. I could be wrong, but thats my reasoning.
