Chemistry Question: Hydrogen Peroxyde

Post Reply New Topic

At my dentist's recomendation, I need to brush my teeth with Hydrogen Peroxyde, and I just wondered, if it's H202, why don't we just call it Dihydrogen Dioxyde?

Is a chemistry nerd able to enlighten me here?

People don't like to change familiar names.

I think it's more informative to keep the word peroxide in there as it gives a better clue to reactivity.

IUPAC would also have us refer to water as dihydrogen monoxide. Feel like changing to that name?

No need, really. Why does it matter?

^ It's an Aspie thing...

I'm autistic and into chemistry, but this does not concern me.

I'm autistic and took chemistry classes to earn my engineering degree, but this does not really concern me, either.

No one is going to answer this guy's question, for lack of giving a crap.

According to my brief google search, it was named before the IUPAC naming system came out. Regardless, I'd say that many chemicals have common names that are used in replace of their technical or IUPAC names. For example, Acetone is a common one, but it's formal name is Propan-2-one. Wouldn't want to go around saying that all the time, would we?

Dihydrogen monoxide is the latest threat to America's youth!

Once you start 'doing' it - its is instantly addicting!

In fact- Ive never heard of ANY one ever giving up dihydrogen monoxide, and living!

Its better known by its "street name" though.

alright, the prefix "per" is used in chemistry to mean 'one more than the usual'--just as "sesqui" means 'one and a half'--

Hydrochloric acid is the one that annoys me the most. I mean, you could argue that's a tautology. It's also inconsistent with all the other common acids. Nobody ever used hydrosulfuric acid or hydronitric acid, and let's not even get started on the carboxylic acids and by extension other organic molecules...
