which halogens give a positive beilstein test?
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.
Chlorinated organic compounds are responsible for producing a positive Beilstein test. The production of a green flame during the test indicates the presence of halogens, such as chlorine, bromine, or iodine, in the compound. This test is commonly used to detect the presence of halogen atoms in organic compounds.
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 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 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. :)

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.

The Beilstein test is based on the principle that halogens, when burned in the presence of a copper oxide flame, form a colored flame due to the formation of copper halide salts. The test is used to detect the presence of halogens, particularly chlorine, bromine, and iodine, in organic compounds. The green or blue flame color indicates the presence of a halogen.

yes,it give positive test
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.
I have to do weekly breathalyzer test will Benadryl make me test positive
Formalin gives a positive Fehling's solution test.
Yes, proteins can give a positive iodine test. When iodine reacts with proteins, it forms a complex that results in a brown color change, indicating a positive test for proteins.
