# Name for HxOy compounds?

Is there a name for the class of stand alone molecules that contains oxygen, water, hydrogen peroxide, and ozone? ($\ce{O2}$, $\ce{H2O}$, $\ce{H2O2}$, $\ce{O3}$) I would not want to include hydroxyls $\ce{OH}$ because they aren't neutral molecules that I can buy.

I think oxide and oxygenate is too generic.

• Oxygen and ozone are oxygen allotropes. Water and peroxide are both hydrogen oxides (dihydrogen di/mono oxides). I don't think there's a name for the four of them. – Molx Sep 7 '15 at 17:16

Not only I've never heard of a name for such a class, but the very choice of compounds seems quite artificial to me. What feature do they have in common?

• Consisting of H and O? That would exclude oxygen and ozone.
• Consisting of H and/or O? That would include $\mathrm H_2$ as well.
• Containing "active oxygen", whatever that might mean? That would exclude water, but include a bunch of inorganic and organic peroxides.
• Oxide is indeed too generic; also, it does not include oxygen and ozone. Oxygenate is even farther off.

Why would you want to have such a class, really?

• The idea was indeed to have a class of compounds that contain an oxygen that can be or is already active. Adsorbing water, ozone, oxygen, or hydrogen peroxide on a TiO2(110) surface for example will all interact with oxygen vacancies present on the surface. (I guess this is more of a surface science kind of question.) I wanted a way to refer to them all without explicitly listing them out each time. I guess there isn't a good way to classify them, thanks for the response! – Coherent Sep 7 '15 at 18:08
• Now that makes things a lot clearer. But is the class really this narrow? Not being quite familiar with surface science, I still have a strong feeling that any alcohol (and maybe almost any other oxygen-containing molecule) would do just as well. Would it not? – Ivan Neretin Sep 7 '15 at 18:16
• Right, I can call organic compounds oxygenates to encompass alcohols, aldehydes, and ketones but I wasn't sure if there was a term I could use as easily for those without carbon essentially. Thanks for the input! – Coherent Sep 7 '15 at 20:56
