Comment on Apart from water and salt, are there any inorganic foods?

  That’s a false statement. It needs to have carbon-hydrogen non-ionic bonds for it to be organic. Think carbonic acid vs a ketone of some sort.

    Not really completely false just missing a piece of information- ie I should have mentioned they be bonded but carbonic acid and ketones are both organic compounds so I’m not sure what you’re trying to say there.

      Carbonic acid IS NOT organic.

        According to Wikipedia it is- but I agree after looking at its structure that it is not.

        There are no carbon-hydrogen covalent bonds in the structure.

  Organic compounds don't have a strict consensus based definition today. So any matter of fact statement isn't widely held any longer. It's just one school of thought so to speak.

    You’re right- primarily because science changes as new things are discovered and therefore the definition changes.

    I still think the definition I learned with C-H covalent bonds indicating organic has fewer exceptions than other definitions.

  Calcium carbonate is inorganic because it is a simple salt. Containing hydrogen has nothing to do with it. Ca(HCO3)2 is just as inorganic.

  If you think a molecule needs to contain both H and C to be organic, then fully halogenated propane is inorganic, but as soon as one of the 8 halogen atoms is not substituted it suddenly is organic again. This gets even more absurd with larger molecules like oleic acid C18H34O2. 34 chlorine replacing all H? Inorganic. 33? Organic.

    None of those compounds would be stable. Theoretically you’re making a good point for an exception to C-H bonds defining organic chemistry but I bet all of your fully halogenated compounds would degrade and break apart until some number of hygrogens replace the halogens to make it stable.

    Point taken tho.

      What do you mean would not be stable…? They are more stable than then hydrogenated versions. PTFE is essentially only C and F in endless chain of [CF2].
