An overwhelming majority of what we eat is made from plants and animals. This means that composition of our almost entire food is chemicals from the realm of organic chemistry (carbon-based large molecules). Water and salt are two prominent examples of non-organic foodstuffs - which come from the realm of inorganic chemistry. Beside some medicines is there any more non-organic foods? Can we eat rocks, salts, metals, oxides… and I just don’t know that?
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].
