    Fluorine can also 'oxidise' oxygen, the only element which can. Oxygen itself is a vicious element already, easily oxidises chlorine, right the way to perchlorate.

    • @andygrove285
      @andygrove285 2 роки тому +6

      ​@@Paonporteur You are incorrect my friend. There is an entire series of halogen oxides (excluding fluorine). For example chlorine dioxide used to disinfect water, and also corresponding chlorine oxyacids and ionic compounds of them, for example perchloric acid and potassium perchlorate.
      And, there is a series of oxygen fluorides, for example dioxygen difluoride.
      Also take a look at compounds like perchloryl fluoride and nitryl fluoride for even more wackiness.
      A simple look at the Periodic Table will explain what is and isn't possible in terms of what can oxidise what.
      I think you are talking about 02, dioxygen, which is already reacted - with itself, as I mentioned in my first comment.

    • @hungarianheroes
      @hungarianheroes Рік тому

      ​@@andygrove285 Things doesn't work this simple Just because a compound exists it doesn't mean you can synthesize it from its constituent elements. For example Ag2O, Au2O3 and HgO all exists, but still, you can't make them by burning the corresponding metal. The same is true for a lot of halogene oxides. (Also F2 only reacts with O2 using an electric discharge, so I wouldn't call it a simple oxidation.) Also checking the ptable for electronegativities won't tell you everything about an element's reactivity.

    • @andygrove285
      @andygrove285 Рік тому

      ​@@hungarianheroes What are you talking about? Can fluorine oxidise oxygen? The answer is yes. Can oxygen oxidise halogens, except fluorine - again yes. Please take time to read my comments. I said nothing about direct synthesis or any method of preparation. Furthermore, you are considering molecular dioxgen, so your logic is flawed anyway.
      It seems yourself and our friend @Sweet bromine are considering oxidation in layman's terms, meaning like element/compound X reacts with oxygen to produce an oxide. In chemistry terms, oxidation is the process whereby an atom, ion or molecule loses electrons. Fluorine can pull an electron from just about any other element, even oxygen. Oxygen can pull electrons from just about any other element, except fluorine. There may be other bizarre cases, such as excimers or something, but, at STP it's generally true. Of course, the noble gases are extremely difficult, or impossible to oxidise due to their electronic stability. However, xenon fluorides do exist for example.

And, once again, it seems pretty clear that both yourself and sweetbromine are considering plain, chemistry 101 reactions with molecular oxygen which is itself a compound. In any case, I hope the situation is now clear.

      @SIMKINETICS 9 років тому +16

      Miikka Silfverberg Yes, but the first impression seems ironic or counter-intuitive unless one knows about chemistry. I'm a retired engineer whose last project was to re-design a specialized electroplating instrument that was being destroyed by a wide variety of very harsh chemistry used for electroplating several metals, including platinum, gold, iridium, nickel, zinc, titanium & others. The project was challenging because nearly all the working parts, including high & low voltage electronics, structures, containers, valves, pressure/vacuum controls, which had to be replaced with mostly teflon-coated components, platinum or 316 stainless. Then, there were gobs of tubing & fittings to replace (all FEP, PEEK or teflon). Chemistry run through it included concentrated acids & bases at both ends of the PH scale, bleach, hydrogen peroxide and piranha. Lots of pricey, specialized labware were required. Although I had worked with many chemists for decades, that final project really got me thinking about & researching inert materials. Chemistry was never my strong suit, so it was an education for me.
      Generally, I've got to say that automating chemistry processes was very interesting work, and direly needed to keep PhD lab-rats from becoming disenchanted with the tedium in their lab work. I'd recommend to engineering students that they get a good dose of chemistry & really learn it well because the demand for engineers will focus in that professional arena and other scientific endeavors involving chemistry as part of a process. Increasingly, engineering is becoming mostly scientific.

      As far as I could understand, they present several reasons why fluorination could be useful in increasing bio-availability. Stability is one of them. In Section 2, they seem to explain how increased stability of the fluorinated compounds increases bio-availability: it makes them more resistant to metabolic enzymes and thus more likely to reach the site where they can be medically active.
      However, as far as I understood, they also say fluorination can modify the basicity or acidity of parts of the compound, increase binding affinity to proteins and change the form of the compound (or rather the preference between different isomers of the molecule). A lot of factors besides stability are at play apparently! Both properties of fluorine itself and properties of the target protein factor in. The combination of biology and chemistry is really interesting! Though it also seems quite tricky :)

    it would be really cool to have a "fluorine lighter". the fuel is yellow, it ignites anything even if its raining, it burns tru metal, no flame... the difficult thing would be recharging it and maybe using it without blowing up in the attempt xD.
    also 5:04 that should smelled horrible, am I right?

    • @kyleclegg89
      @kyleclegg89 9 років тому +9

      Pure fluorine, along with most other elements, is difficult to get. Also, fluorine would probably react with all the chemicals in the lighter. Other than the expense and reactivity, that would work.

    Do these fluoride compounds enter the blood supply when ingested (like tin fluoride or whichever type of fluoride is added to some water supplies). If so, is it possible that ingesting fluoride compounds could become dangerous when these compounds come into contact with reactive intermediates especially during the normal metabolic process? Such as reactive oxygen species or other radical species? I used fluvoxamine, a fluorine containing anti depressant for a little while so i know fluorine is a great enzyme de- activator.
