There is not a clear definition available on either cases. As it is mentioned above, the naturally occurring compounds in living organisms are usually called as Organic compounds. This is vague in many cases, but almost true to cover the definition of ‘organic’.
But Glynn’s definition of ‘inorganic compound’ is too ambiguous. There are non-synthesized compounds inside inorganic classes too. A simple example is Water (H2O). There is no Carbon in it. You can even synthesize an organic compound from inorganic reactants.
