halogen containing compound
Compounds that contain halogens (chlorine, bromine, iodine) are responsible for producing a positive Beilstein test. The test detects the presence of halogens by forming a blue-green flame when the compound is heated with copper oxide in a flame.
Chlorine, bromine, and iodine give a positive Beilstein test. The test involves ignition of a compound in the presence of copper oxide, which forms a green flame due to the halogen present in the compound.
The Beilstein test is a simple chemical test used to test for halides. A positive test result is indicated by a green flame which is caused by the formation of a copper halide. This test is not used often because of the possibility of generating highly toxic chloro-dioxins if the test material is a polychloroarene.
The purpose of the Beilstein test in organic chemistry is to detect the presence of halogens, specifically chlorine, bromine, or iodine, in organic compounds. This test involves heating the compound with copper oxide in a flame, resulting in a colored flame that indicates the presence of halogens.
The Beilstein test is a simple chemical test used in chemistry as a qualitative test for halides. It was developed by Friedrich Konrad Beilstein.[1] A copper wire is cleaned and heated in a Bunsen burner flame to form a coating of copper(II) oxide. It is then dipped in the sample to be tested and once again heated in a flame. A positive test is indicated by a green flame caused by the formation of a copper halide. This test is little used nowadays; one reason why it is not popular is that it is possible to generate the highly toxic chloro-dioxins if the test material is a polychloroarene.[2] An alternative wet test for halide is the sodium fusion test - this test converts organic material to inorganic salts include the sodium halide. Addition of silver nitrate solution causes any halides to precipitate as the respective silver halide. :)

Copper is the element responsible for the green flame produced in the Beilstein test. When a copper compound is heated in the presence of a flame, it emits a green color due to the presence of copper ions.
Chlorine, bromine, and iodine give a positive Beilstein test. The test involves ignition of a compound in the presence of copper oxide, which forms a green flame due to the halogen present in the compound.

Because in a Belstein test, the copper halide should be able to volatilize to produce green flame, an indication that a halogen is present in the compound. Copper fluoride is not volatile., hence this kind of test is not suitable for the detection of fluorine.
