Возможно, вы имели в виду: baeyer test positive result |
Remember that a positive Baeyer's test or potassium permanganate test is indicated by a change in color from deep purple to brown . This is because the deep purple permanganate ion gets reduced to form a brown precipitate of $Mn{O_2}$. A negative result is a deep purple with no formation of precipitate.
The baeyers test is used to test for an unsaturated carbon carbon bond, such as an alkene or alkyne, but not an aromatic carbon carbon bond. |
