How do you test for organic compounds?

Organic compounds contain carbon atoms covalently bonded to hydrogen atoms and in some case hetero atoms like $\mathrm{N},\mathrm{O},\mathrm{S}$. The Organic compound can be detected through:

1. Infrared spectroscopy: To determine functional groups.
2. Nuclear magnetic resonance spectroscopy: To determine the whole structure of an organic compound.
3. X-ray: To determine the crystal structure.
4. Mass spectrometry: To determine the molecular weight of a compound.

Therefore, the above mentioned points can easily detect organic compounds.
