Determination the compound is organic or inorganic

Click For Summary
SUMMARY

To determine if an unknown compound is organic or inorganic, combusting the compound in pure oxygen and analyzing the combustion products for carbon dioxide and water is a primary method. However, this approach is ineffective for certain organic compounds, such as carbon tetrachloride (CCl4), which lacks hydrogen and is non-combustible. There is no definitive chemical test to distinguish between organic and inorganic compounds, as the classification is often arbitrary and context-dependent. A comprehensive analysis of the compound's physical and chemical properties is necessary for accurate identification.

PREREQUISITES
  • Understanding of combustion analysis techniques
  • Knowledge of organic and inorganic chemistry classifications
  • Familiarity with chemical properties of compounds
  • Experience with laboratory safety protocols
NEXT STEPS
  • Research combustion analysis methods for organic compounds
  • Study the properties of carbon tetrachloride (CCl4) and its implications
  • Explore the classification criteria for organic vs. inorganic compounds
  • Learn about physical and chemical property measurement techniques
USEFUL FOR

Chemists, laboratory technicians, and students studying organic and inorganic chemistry will benefit from this discussion, particularly those interested in compound identification and analysis techniques.

Dear Fellow Members,
If we have been given an unknown compound.We even don't know that it is organic or inorganic. Is there any chemical test to determine that the compound is organic or inorganic.. Please Help me out.


Thanks...

You just have to combust the compound in pure oxygen and test the combustion products for presence of carbon dioxide and water. This does not work for some organic compounds, like carbon tetrachloride, though. (CCl4 does not contain hydrogen and is not combustible)
 
There is no chemical test available for differentiating between organic & inorganic..?
 
The short answer is that the line is somewhat arbitrary. These labels are useful in general to organize classes, journals, meetings etc.

What would you call ferrous citrate, sodium carbonate?

IMO, its not a very fun question to ask because in the real world you'd have some context about unknown compounds and would be more interested in, for example, if its pure, is it safe, is it volatile, does it have color.

Either way, the long answer is that you likely cannot do one single test to conclusively say that a compound is one or the other. You would have to infer that from measuring its physical and chemical properties in a variety of ways to get to a narrow list of candidates which, if you are lucky, will have properties allowing differentiation amongst them.
