Externet Posted July 13, 2005 Share Posted July 13, 2005 Hi. As I know nothing in the subject, am asking if isopropyl is inorganic, and which other alcohols are produced from inorganic chemicals not derived from petroleum. Thanks, Miguel Link to comment Share on other sites More sharing options...
jdurg Posted July 13, 2005 Share Posted July 13, 2005 There is no such thing as an inorganic alcohol. Alcohols are hydrocarbon based molecules with a single -OH functional group. Isopropanol is an organic compound. It's formula is H3C-CH(-OH)-CH3. For a compound to be an 'inorganic alcohol', it would have to be a non hydrocarbon base chain with an OH group. Those are known as bases. (NaOH, KOH, Ba(OH)2, etc.) Link to comment Share on other sites More sharing options...

(NaOH, KOH, Ba(OH)2, etc.) Not only bases, also a lot of acids, such as SO2(OH)2, PO(OH)3, HPO(OH)2 (sulphuric acid, phosphoric acid and phosphorus acid). As a rule of thumb, inorganic compounds of the form X(OH)n or XOm(OH)n are basic if X is in a low oxidation state (1, 2 and sometimes 3), amphoteric if X has an intermediate oxidation state (4, 3, sometimes 2) and acidic if X has a high oxidation state (>= 4). There is also NH2OH, which is slightly basic, but not because of its OH group, but in a similar way as NH3 is basic, by accepting a proton, forming NH3OH(+).

jowrose Posted January 26, 2006 Share Posted January 26, 2006 So sulfuric acid has the structure H-O-O-S-O-O-H ? Link to comment Share on other sites More sharing options...
woelen Posted January 26, 2006 Share Posted January 26, 2006 No, sulfuric acid has structure O2S(OH)2, so all four oxygens directly bonded to the S. Two oxygens have a H atom attached. There is no H atom attached to the S. The oxygens, bonded to the S, without the H on them, have a double bond, all other bonds are single. Link to comment Share on other sites More sharing options...
Ilja Posted January 27, 2006 Share Posted January 27, 2006 So sulfuric acid has the structure H-O-O-S-O-O-H ? just a clue there would be "peroxo" in the name if there are any O-O bondings. Link to comment Share on other sites More sharing options...
jowrose Posted January 27, 2006 Share Posted January 27, 2006 ah ok. I wondered what that meant. thanks. Link to comment Share on other sites More sharing options...
woelen Posted January 28, 2006 Share Posted January 28, 2006 ah ok. I wondered what that meant. thanks. An example of such a peroxo acid is Caro's acid and peroxodisulfuruc acid: Caro's acid: O2S(OH)(OOH), H2SO5 Peroxosulfuric acid: O2(OH)SOOSO2(OH), H2S2O8 Link to comment Share on other sites More sharing options...
mississippichem Posted March 27, 2010 Share Posted March 27, 2010 The closest thing I can think of would be other Group IV -OH compounds. "Silanols" contain the moiety Si-OH, and are often found as functional groups on organic compounds. They actually make great precursors to silicones, that is, polymers with the [si-O-Si-O]... linkage. Germanols also exist but are highly labile and a very pH sensitive. Lead can form hydroxo complexes but some of them have fleeting stability as OH^- is a fairly hard base and Pb ions are fairly acids. Link to comment Share on other sites More sharing options...
