    Hi Bryson I hope you are doing well. I have been watching your UA-cam videos since at the start of sixth form college. I'm still subscribed to this channel. I did BTEC Applied Science from 2020 to 2022. I want to say thank you so much for your help because without the existence of this channel, I wouldn't have no chemistry knowledge. Currently, I am in my third of university studying forensic science and after this I will be progressing to my fourth year!

    • @BrysonChemistry
      @BrysonChemistry 6 днів тому

      All group 7 elements are diatomic and non-polar molecules. As such, they only have van der Waal’s forces of attraction between molecules. As you go down the group, the molecules become bigger and have more electrons. This means the van der Waals forces are stronger and more energy is needed to overcome these forces…this results in a higher boiling point

    Why is experimental value higher than expected? Is it because there is higher than expected energy released from the formation of ionic bonds?

    • @BrysonChemistry

      No, it’s because the experimental value will include any covalent character if it’s present

    • @BrysonChemistry
      @BrysonChemistry Місяць тому

      Yes, that would work if you were naming it as an alkane with a side chain containing Cl. It’s more common to name the molecule by its functional group though, in this case a halogenoalkane…this means it has to be in the longest chain

    How do you know that the long line is a methyl? 4:50

    • @BrysonChemistry
      @BrysonChemistry 2 місяці тому

      The line represents a bond. If there’s no atom shown at the end of the bond then you know it’s a C atom…you also know that C has to have 4 bonds and in skeletal we don’t show C-H bonds…so the C at the end of the line must have 3 H’s bonds to it…so it’s a CH3 group which is a methyl

  • @annie_furrealz

    Thanks for the helpful video! Why do ionic compounds with covalent character have a lower melting point than expected please?

    • @BrysonChemistry
      @BrysonChemistry 6 місяців тому

      This is an awkward one to explain easily…since large lattice enthalpy should mean higher melting point right? But it’s not the case when it comes to large amount of covalent character…I’ll try to explain in the most simple way. If it’s 100% ionic then all ionic bonds need to be broken in order for ions to move freely. If it has covalent character then all bonds don’t have to be broken for the ions to move freely, meaning the melting point is lower despite the fact that the lattice enthalpy is more exothermic. Lattice enthalpy isn’t the same as melting, lattice enthalpy is from (g) state and involves all bonds to fully separate ions, not just enough energy to allow them to move. Hope this helps??
