    I've been retaking my A level chemistry exam by myself this year cause i need an A and your vids are the only thing helping me push my grade up. Just wanted to tell you thank you so much for the vids.

    Sir,my book has the structure you made at 11:53 and it says underneath it
    "According to this molecular orbital picture each c-c bond in benzene consists of full sigma and half pi bond.Because of this reason c-c bond is equal and benzene shows substitution as well as additional reaction"
    Could you kindly elaborate this? I don't get it any of it.

    August Kekule was "energetic and intense" I'm not sure what he took if he did take anything, or if being German had something to do with him, but you should speed up your thoughts a little. tea is great( green tea, caffeine and theanine), but I recommend espresso.

    Hello, thank you for all your help sir, I really understand this well now :) ,
    I just had one question or confusion, you know the electron configuration of c is 1s2,2s2,2p2 so the carbon has 2 electrons in its outer shell ? Where does the 2 other electrons come from. I did research and hybridization kept coming up it was hard to understand and if this is the case do all atoms undergo hybridization or is carbon an exception.
    Thanks for your help

    Hi, thank you so much for your videos!! You make learning Chemistry bearable :P are you going to be doing anymore videos for F324 and F325 or have you finished now?

    • @MaChemGuy
      @MaChemGuy  9 ปีที่แล้ว +3

      Thanks for the comment, glad the videos help. I'm struggling to find the time to make any more at the moment. Hopefully I'll be able to do a few more over Easter but my original plan to have the whole of F324 and F325 done this year isn't looking likely at present. Thanks again and keep watching!

    Why does benzene evaporate in room temperature when its stable

    • @anametobenamed3717
      @anametobenamed3717 6 ปีที่แล้ว

      DEAdmanstree 2ok It's chemically stable. It's volatile because they only have induced-dipole intermolecular forces of attraction to keep them together. Benzenes delocalised π electron cloud is good at dissipating electron density so these are especially weak.

  • @aqsasaeed1997
    @aqsasaeed1997 9 ปีที่แล้ว

    It's been a while since I've done AS so I feel like I've forgotten the basics but can someone explain how each carbon has four electrons, three form sigma bonds and 1 forms a pi bond when there's four outer electrons so shouldn't it be 1s^2, 2s^2 making the fourth electron still in the s?

    • @shumi3735
      @shumi3735 9 ปีที่แล้ว

      +A Saeed I know that the first bond a carbon atom makes with another atom is always a sigma bond and if it has a second or third bond with that atom, those are pi bonds.
      In benzene there are 3 double bonds so each carbon has a double bond with another carbon and a single bond with a carbon and a hydrogen.
      So the bonds that the carbon has to the hydrogen and the singly bonded carbon are both sigma bonds (its the first and only bond the carbon has with the other atom) but in the case of the carbon-carbon double bond one of the bonds is sigma so the second has to be a pi bond.
      So that's why there are 3 sigma bonds and 1 pi bond, I think.
      Hahahha i hope I'm correct and I hope this helps :) Its something to do with hybridization I think but I don't know much about that, its not on my curriculum.
