by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
react it with bromine water
test for unsaturated compounds in which potassium permanganate is used.
Basically there are many tests which is usually practiced to distinguish saturated Organic compounds from the unsaturated ones. But two of them are the most common: 1. Bromine water test. 2. Bayer's test. Basically Bromine water is red in color, so when an unsaturated compound (Alkene or Alkyne) is treated with it. The Bromine water get decolourized, on the other side the color is not changed when treated with saturated compound. In the Bayer's test KMnO4 solution is used, the unsaturated compound vanish its pink color while the saturated compounds do not.
ethene: CH2=Ch2 propene: CH2=CH3CH There is nowhere else to place a double bond! (C=C) No number is used in the names ethene and propene because the number would be useless as the double bond is located at carbon "1"
tollen's test, fehling's test, iodoform test
It will be cheaper, since you do not have to make chloroalkane first.
test for unsaturated compounds in which potassium permanganate is used.
bromine water can be used to test whether the compund is saturated or unsaturated.
This reagent is bromine in solution.
baeyers test is test for unsaturation gives MnO2 brown ppt withe -enesand -ynes
Ethene can react with Bromine water - turns colourless

Only if the specific test used to detect methadone is used, then the methadone will show up.
To test stuff out
It will show up if the specific test used to detect it is used.
