There is no colour change
i think the unsaturated fat decolourises it :/
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
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.
The unsaturated compounds having double or triple bonds under go the addition reactions with Bromine water, ethanol does not have the double or triple bonds
add bromine water. unsaturated compounds will decolourize bromine water
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.
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
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.
bromine water can be used to test whether the compund is saturated or unsaturated.
Unsaturated hydrocarbons such as alkenes and alkynes will decolourize bromine water.
i think the unsaturated fat decolourises it :/
An unsaturated oil will decolorize bromine water.
Saturated hydrocarbon does not decolourise bromine water while unsaturated hydrocarbon decolourize it.
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
bromine water is oxidising in nature. it removes the double bonds and attaches itself to the alkene.
