So does that mean that hypoflourites are some of those compounds that all you have to do is look at them and then BOOM!
They do not explode easily, but they quickly decompose. Indeed HFO is synthesised, but it is decomposed quickly and never was created in more than trace amounts.
The ion FO(-) also is very elusive and certainly not something the home/citizen chemist can make. So, you can make chloroform, bromoform and iodoform from the halogen and an alkaline acetone solution, but when fluorine is passed through an alkaline solution with acetone in it, then I'm quite sure that no fluoroform is formed.
Fluorine is so different from the other halogens, the only thing which coincides is the type of formula (F2, Cl2, Br2, I2), but in its chemical reaction it is VERY different. Just as all other elements in the same row differ a lot from the other elements in the same colums (e.g. O vs. S, Se, Te, and N vs. P, As, Sb, Bi). For the heavier elements there is a certain gradual change of properties, but the first element is anolamous.
