Determination the compound is organic or inorganic

Click For Summary

Discussion Overview

The discussion revolves around methods to determine whether an unknown compound is organic or inorganic. Participants explore the feasibility of chemical tests and the inherent challenges in categorizing compounds based on their properties.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests combusting the compound in pure oxygen and testing for carbon dioxide and water as a method to identify organic compounds, noting limitations with certain compounds like carbon tetrachloride.
  • Another participant questions the existence of a definitive chemical test for differentiating organic and inorganic compounds.
  • A different viewpoint emphasizes the arbitrary nature of the organic/inorganic classification, citing examples like ferrous citrate and sodium carbonate, and suggesting that context is crucial in real-world scenarios.
  • It is proposed that no single test can conclusively categorize a compound, and that a comprehensive analysis of physical and chemical properties is necessary to narrow down possibilities.

Areas of Agreement / Disagreement

Participants express differing opinions on the existence and effectiveness of chemical tests for distinguishing organic from inorganic compounds, indicating that multiple competing views remain without a consensus.

Contextual Notes

Limitations include the arbitrary nature of organic/inorganic classifications and the dependence on context for evaluating unknown compounds. The discussion highlights the complexity of categorizing compounds based on a single test.

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.
