Determination the compound is organic or inorganic

[Deadevil]

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.

Dear Fellow Member,

There are several chemical tests that can be performed to determine whether a compound is organic or inorganic. One common test is the elemental analysis, which involves analyzing the compound's composition of elements and comparing it to known organic and inorganic compounds. Another test is the solubility test, where the compound is dissolved in water and organic solvents to see if it is soluble in both or just one. Additionally, organic compounds usually have a characteristic odor, so smelling the compound can also provide some clues. However, the most accurate way to determine if a compound is organic or inorganic is through spectroscopy techniques such as infrared spectroscopy or nuclear magnetic resonance spectroscopy. These tests can provide information about the functional groups and molecular structure of the compound, which can help identify its organic or inorganic nature. I hope this helps in your analysis. Best of luck!

Sincerely,
