In the beginning, chemists proposed that organic compounds could only be made by living organisms.

The German chemist Friedrich Wohler had synthesized urea before it was found in living organisms.

Besides carbon and hydrogen, organic compounds can contain all the elements in the periodic table.

Organic compounds typically have low melting and boiling points, are insoluble in water, and are lighter than water because they are made from polar bonds.

Organic compounds burn easily since the main components of their molecules are carbon and hydrogen.

Our bodies digest different organic foods that supply us with energy for various activities and the materials needed to maintain the cells.

All organic compounds found in nature have been synthesized by chemists in laboratory.

Organic compounds prepared by chemists are not completely identical to those occurring in nature.

Inorganic compounds do not contain elements like carbon and hydrogen.
