The distinction between inorganic and organic compounds is important because the two types of compounds have different properties. Inorganic compounds are typically more stable and less reactive than organic compounds. They are also more likely to be found in nature. Organic compounds, on the other hand, are more reactive and less stable than inorganic compounds. They are also more likely to be found in living things.

Here are some examples of inorganic and organic compounds:

• Inorganic compounds:
  • Water (H2O)
  • Carbon dioxide (CO2)
