Title: Tetranitromethane and similar chemicals
Post by: budullewraagh on July 28, 2004, 02:27:49 PM
i know that C(NO2)4 exists and is a rocket propellant.  i checked my merck index for a chemical that is the same but with added H on every O which would reduce each N to +3.  i could not find this.  does it exist?

Such as species doesn't exist, except in calculations and possibly in some really screwy gas phase unstable state.

that's a shame.  how about FH7?  fluorine can do the whole +7 thing but i don't understand how.

I'd have to give that one the big 'no', too.

yeah well i tried.  what oxidizes a fluorine atom??  nitrates do but i still dont get how that could happen.  odd.

Nitrates oxidize a fluorine atom?  This is news to me.  I don't know of much that can oxidize fluorine the atom, or the diatomic molecule.

From webelements, I think there are nitrogen-fluorine combo's:

If you look under nitrogen, it lists fluorides, but if you look under fluorine by itself, you don't get jack. Maybe the table is incomplete?

FNO3 exists; it's used as an oxidizing agent in rockets.  F can get to +7, which makes me scratch my head.

FNO3 may exist, but it doesn't mean that you used a nitrate to oxidize fluorine.

so what do you think oxidized the fluorine?  a permanganate?

Depends.  What was the reaction that produced it?  Did you start with NO2F?  Did you start with F2 and NO, NO2 or something along those lines?  Perhaps it was done with ridiculous temperatures?  Try looking up that compound to find the references for it.  That will give you a lot better idea about it.
