In these chemical compounds, C is for carbon, O is for oxygen, N is for nitrogen, and K is for potassium.

Which chemical compound is most likely inorganic?

The compound that contain K is most likely to be inorganic.

Explanation:

Organic compounds are generally composed of carbon, oxygen and nitrogen. In other words it can be stated that carbon, oxygen and nitrogen builds the structural entity of various organic compounds.

For example carbohydrate glucose contain carbon, hydrogen and oxygen. The amino acids of protein contain carbon, nitrogen, oxygen and hydrogen.

On the other hand potassium is present in various inorganic compounds such as potassium chloride (KCl), Potassium permanganate (KMnO4) etc.
