Why na2co3 is an inorganic compound?

Answer 1

It was already 'discovered' and named, before organic chemistry was 'developed',

Anyhow, organic means 'from life' and there is more carbonate outside than inside 'living' things.

Answer 2

Na2CO3, also known as sodium carbonate, is considered an inorganic compound because it does not contain carbon-hydrogen (C-H) bonds, which are typically present in organic compounds. Inorganic compounds are generally derived from non-living matter and do not contain carbon-hydrogen bonds in their structure. Sodium carbonate is composed of sodium ions and carbonate ions, making it a classic example of an inorganic compound.
