I'm trying to design a pseudo-educational game turning elements into compounds into bigger compounds. This uses only the elements Hydrogen, Carbon, Nitrogen, and Oxygen.

I'm looking for common and/or naturally occurring compounds that contain 2-9 atoms and only those four elements. So far, I have:

O2 Oxygen
H2 Hydrogen
N2 Nitrogen
CO Carbon Monoxide
O3 Ozone
H2O Water
N2O Nitrous Oxide
HCN Hydrogen Cyanide
NO2 Nitrogen Dioxide
CO2 Carbon Dioxide
CH2O Formaldahyde
H2O2 Hydrogen Peroxide
NH3 Ammonia
CH202 Formic Acid
HNO3 Nitric Acid
CH4O Methanol
H2CO3 Carbonic Acid
N2H4 Hydrazine
C2H4 Methane
H4N2CO Urea
C2H4O2 Acetic Acid
NH4NO3 Ammonium Nitrate
C2H6O Ethanol
C3H4O2 Acrylic Acid


I have deliberately left out Ethane, Methyl, and Ethyl. Anything good I'm missing?

[hrothgar]

There is something out there called H30

[Elianna]

Methane is CH4, not C2H4.

I'd seen stuff like this before, but it keeps catching me up. For example, carbamic acid, while it has a name, doesn't actually exist. I'm only looking for stable stuff, that either is common or natural.

Thanks for catching that typo, Elianna!

NO3, heavenly gase

Not sure what NO3 is.

Nitrous Oxide (more correctly dinitrogen monoxide or N2O) is laughing gas (used in surgeries). Jtfanclub already has this.

Also, there's NO2 (nitrogen dioxide), which is an air pollutant. When it heats up, it forms ditrogen tetraoxide (N2O4) which looks browner, and is one of the components of smog (if I remember 7th grade correctly).

Been years since I looked at chemistry, but itsn't C4 diamond?

No, a diamond is a macro-molecule. You need many carbon atoms before you can destinguish diamond from other forms of carbon.

And C4 would be highly unstable as the covalent bonds prefer to be widely spaced appart. Maybe a tedrahedron-shaped (or diamond-shaped, lol) C4 molecule could exist in vacuum.

C60 exists as a stable molecule, though. It's called buchmeisterfulerene or just fulerene. Some older textbooks call it fussballene because the atoms are aranged in the exact same way as the joints in an old-fashioned football (am=soccer) ball. Nowadays football balls are sewn in a different way, but I don't think that's the reason why the molecule changed its name.

[Gerben42]

With two Carbons it gets more complicated, for example:

C2H6 = ethane
C2H4 = ethene
C2H2 = ethyne

H3C-CH2-OH = ethanol
H2C=CH-OH = ethenol
H-C_=C-OH = ehtynol

I'm sure there would be systematic names for things like:

N-C-OH
N-C-COOH
H2N-C-COH
etc.

but chemistry was a long time ago

Btw is there also a mini-buckyball? C30 in dodecaeder-shape?

Apparently not. Not sure why. Maybe it's just that nobody has invented a way of syntezising it.

[FrancesHinden]

It's a long time since I did any chemistry, but are your names a mix of SI and traditional?

[Gerben42]

Of course since each C-atom is in 3 of the pentagons you would need 20 of them, making it C20. This DOES exist but is not very stable, apparently (pentagons sharing edges cause instability). C20H20 is stable, though (dodecahedron with Hydrogen at each corner).

[Al_U_Card]

Try the IUPAC website (International Union of Pure and Applied Chemistry) they are the responsible body for nomenclature issues.

Ooh...NTO! How did I forget NTO? (N2O4, big time rocket fuel from the 50s and 60s).

I also added Oxalic Acid (C2H4O2), Acryllic Acid (C3H4O2) and Propylene (C3H6), though I'm trying to stay away from the less common compounds, especially if they're just one atom away from something common.

I am trying to fix all of them to Empirical formula as well.
