A positive test for an alkene is the addition of bromine water, which will turn from orange/red to colorless when it reacts with the alkene due to halogenation of the double bond. This test is used to confirm the presence of alkenes.
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.
Baeyer's test for unsaturation using KMnO4 . if the sol'n retains the purple color of the reagent , then it is an alkane. if the color disappears with formation of brown precipitate ,it indicates presence of unsaturated HC
Turpentine is a mixture of compounds primarily containing terpenes, which are cyclic hydrocarbons known as alkene.
C5H10 can be both an alkane and an alkene. As an alkane, it would be pentane (C5H12), and as an alkene, it would be 1-pentene (C5H10). The presence or absence of a double bond in the molecule determines if it is an alkane or an alkene.
The DNA test result is positive.
It means that it tests positive for either aldehyde, alkene, or phenol functional groups.
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.

Adderall will test positive for amphetamine. It is an amphetamine therefore it will test positive for such.
Will test positive for Benzodiazepines
if montoux test is positive
In the bromine test, an alkene compound will decolorize a bromine solution whereas an aromatic compound will not react with the bromine solution. This is because the double bond in the alkene readily reacts with bromine to form a colorless product, while the stable aromatic ring in the aromatic compound does not undergo such reaction.
1-nonene is an alkene, as it contains a carbon-carbon double bond.
C5H10 can be both an alkane and an alkene. As an alkane, it would be pentane (C5H12), and as an alkene, it would be 1-pentene (C5H10). The presence or absence of a double bond in the molecule determines if it is an alkane or an alkene.
