Why are organic compounds usually more complex than inorganic compounds?

The major difference between inorganic and organic compounds is that inorganic compounds are usually?

• Answer:

  Inorganic compounds are usually not composed of carbon and hydrogen atoms. Organic compounds are composed of carbon and hydrogen, although sometimes the hydrogen atoms get replaced by other elements. Sodium chloride, a very important compound in living things, is composes of sodium (Na) and chlorine (Cl), and is inorganic. Iron oxide, Fe2O3 is rust, composed of the metal iron and the element oxygen, and is also inorganic. The carbohydrate glucose, essential to life, has the molecular formula C6H12O6, which contains carbon and hydrogen, as well as oxygen, and is organic. Methane, CH4, is the simplest hydrocarbon and is natural gas used for powering appliances in some homes, and is also an organic compound.
