Presence of halogen in organic compounds can be detected using:
Presence of halogen in organic compounds can be detected using:
The correct option is D Beilstein test
The
Beilstein test is a simple qualitative chemical test for halides. It was
developed by Friedrich Konrad Beilstein. 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.
This is
a test for the detection of halogens. In this test a copper wire is heated till
it stops imparting blue colour to the flame. Then the compound is touched with
wire and again heated. If it again imparts blue colour it indicates the
presence of some halogen. This test does not tell us which particular halogen
is present. Moreover, there are many compounds which do not contain any halogen
but give this test.
