Simple distinguished test between saturated and unsaturated compounds?
add bromine water. unsaturated compounds will decolourize bromine water
What simple chemical test will distinguish an alkane from others?
Use bromine water (Br2) or acidified permanganate (H+/MnO4-) With permanganate: add the permanganate to the alkane and no reaction will occur, add the permanganate to the alkene and you will form a diol the solution will also turn from purple to colourless. With bromine water: add the bromine water to the alkane (plus you need sunlight) and you get a substitution reaction, this is a slow reaction. Add the bromine water to the alkene and you get an immediate addition reaction (this one does not need sunlight). When bromine water reacts with an alkene it is decolourised, the reddish brown bromine water turns from brown to colourless. This is because alkenes are unsaturated and contain a carbon to carbon double bond. If you did the bromine water test in a dark place say a cupboard then the alkene would decolourise but the alkane wouldn't because it needs UV/sunlight in order to react. in practice the cupboard is not necessary as the speed of decolourisation is so much faster with the alkene.
What functional groups does bromine in chloroform test for?
Alkenes
What reagent is used to test for unsaturated hydrocarbons?
This reagent is bromine in solution.
What substance is added to an organic molecule to test for the degree of saturation?
Bromine
How can bromine water test the difference between alkanes and alkenes?
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
What test is used to show that ethene is unsaturated?
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.
Simple distinguished test between saturated and unsaturated compounds?
add bromine water. unsaturated compounds will decolourize bromine water
What is a simple chemical test to distinguish between bezene and hexane answer?
bromine water test
What test distinguishes between alkene and alcohol?
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
What is the difference between bromine water and liquid bromine?
Liquid bromine is the Real Bromine, while Bromine water is a mixture of Bromine and Water
Why should excess bromine water be avoided in the test for free tryptophan?
The presence of excess bromine water will cause the pink color to disappear and it may be masked by the color of the reagent.
What is the difference between bromine and liquid bromine?
Liquid bromine is the Real Bromine, while Bromine water is a mixture of Bromine and Water
How to down bromine in Hot tub?
Try exposing the water to sunlight, the U.V. will cause the Bromine to burn out more quickly. Also when checking your chemicals keep in mind that most chlorine and bromine free shocks will reactivate a little bit of the old bromine. If you are testing your water for bromine levels try shocking it first, wait a little bit and then test for bromine.
What will you see if you dissolved bromine in water?
You will see Aqueous Bromine or Bromine water
Does hexane and bromine water and sodium hydroxide solution react?
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
Does bromine float in water?
No. Water floats on top of bromine. Bromine's density is over three times that of water.
