# Why doesn't H-O-O-O-O-O-O-O-O-H exist? [duplicate]

The question has its roots in why only carbon mainly shows catenation. I don't see why such a compound cannot be formed. Why don't we have a whole branch dealing with such compounds other than organic chemistry? If this compound can exist then such atoms will also be able to form a large number of compounds like the organic compounds.

• Look at C-C and O-O bond strengths - and compare the O-O bond strength to that of O=O. Same goes for nitrogen (compare N-N single with N-N triple bond). Why can't you just have graphite-like layers of nitrogen? Feb 6 '16 at 11:40
• Computationally it has been predicted that arbitrarily large $\ce{H2O_{x}}$ molecules are technically stable, though after more than a few they are presumably quite shortlived. Feb 6 '16 at 11:41
• @Nicolau Saker Neto so you are saying that what sets carbon apart is its tetravalency and not catenation? Feb 6 '16 at 11:46
• @NicolauSakerNeto Derek Lowe posted on peroxide peroxides. Seems the five-oxygen species is about as long a chain as you're likely to get, even if only fleetingly. Feb 6 '16 at 12:01
• There are other elements which can catenate (boron and sulfur come to mind, iodine and mercury too in certain conditions), but carbon is pretty unique. I don't think any other element is expected to have a similar amount of covalent molecular chemistry Feb 6 '16 at 12:02
