bromine water

For example, when bromine water reacts with cyclohexene, the main product is 1,2-dibromocyclohexane.

To carry out the Bromine test you should add bromine water.

Bromine water is sometimes used instead of chlorine.

If the bromine water becomes decolourised (Goes colorless) then it is unsaturated.

The more Bromine water that is put in, the more unsaturated the unknown sample is.

I used bromine water instead of bromine.

Replies: You already gave the hint: you "used bromine water instead of bromine."

The decolouration of bromine water by electron-rich arenes is used in the bromine test.

Common reactions include use of bromine water to titrate against a sample to deduce the number of double bonds present.

Benzene does not decolourise bromine water as other unsaturated compounds do, so neither of the structures suggested is satisfactory.

When used as bromine water, a small amount of the corresponding bromohydrin is formed as well as the dibromo compound.

For example, phenols and anilines react quickly with chlorine and bromine water to give multiply halogenated products.

The great excess amount of water in bromine water inhibits the reaction of bromine with aluminum in several ways.

The most common compounds that react well with bromine water are phenols, alkenes, enols, the acetyl group, aniline and glucose.

Iron(III) chloride colors its aqueous solution a dark-violet, and bromine water precipitates tribromoresorcin.

Bromine water is a highly oxidizing intense yellow mixture containing diatomic bromine Br at 2.8% dissolved in HO.

So reliable is the reactivity of bromine that bromine water is employed as a reagent to test for the presence of alkenes, phenols, and anilines.

Ethane decolourises bromine water with the formation of 1,2-dibromoethane.This is a test for alkenes as alkanes do not decolourise bromine water.

In this reaction, the terminal aldehyde group is converted to a carboxylic acid group, using selective oxidation of the aldehyde using Bromine water and then converted to gluconate ion.

However, in the case of bromine water reacting with cyclohexene, the solubility of bromine in water is about 0.21 moles per litre, and the concentration of HOBr formed in the equilibrating reaction between bromine and water is about 1.15 x 10 moles per litre.
