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?
i wouldn’t say that bicarbonate or carbonate are organic, as derivatives of carbon dioxide. protonation state shouldn’t change if compound is organic or not
neither is CN-, HCN, HOCN, metal carbonyls, oxalates or oxalic acid. i’d say that phosgene, urea and CCl4 are organic. same goes for higher homologs (HSCN, thiourea, thiophosgene, CS2 and so on)
