    could you start creating questions for each video and then doing videos running through how to do each question?

    Why is the benzene bond described as an intermediate between a single bond and a double bond?

    why do we say -208kj/mol is a smaller number than -360?

      savannah it's exothermic so it releases less energy 🖕🏻

    Why does benzene evaporate in room temperature if it's so stable?

    • @AlleryChemistry
      @AlleryChemistry  7 років тому +4

      Yes. Benzene rings only have van der waals forces holding them together. These forces are week and hence the reason why benzene evaporates readily.

    • @ajx5689
      @ajx5689 7 років тому +4

      Each carbon atom in benzene has one of its outer electrons in a p orbital. Each p orbital overlaps with the neighbouring p orbital and forms a pi bond. This creates a region of space above and below the benzene ring in which the electrons can move within. This makes the electrons delocalised which in turn makes the molecule stable.
      Hope this helps!

      I think it's speaking relative to other structures similar to it

    What exam board is this ?

    • @AlleryChemistry
      @AlleryChemistry  9 років тому +1

      Vanessa SHO this is suitable for all exam boards that offer A level courses.

    What does stability means? why the less enrgy the more stable the compond is.
    Thank you sooo much for your help
