Inorganics are chemicals whose molecules do not contain a carbon-hydrogen bond. This means there are some carbon compounds which are inorganic, for example, carbon dioxide, also all carbonates such as calcium carbonate.

Most carbon compounds, for example proteins, carbohydrates, sugars, vitamins, plastics, and alcohols contain the carbon-hydrogen bond, so are considered ‘organic’.
