Which of the following can Decolourise bromine water?

Which of the following can Decolourise bromine water?

Solution: Butyne, Ethene and Hexyne, all can decolourise bromine water.

Which compound rapidly Decolourises bromine?

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.

What reacts with aqueous bromine?

The most common compounds that react well with bromine water are phenols, alkenes, enols, the acetyl group, aniline, and glucose. In this reaction as well the color of bromine water is changed to colorless from yellow (oxidation process).

Do aldehydes Decolorize bromine water?

The answer is yes. Aldehydes will decolourise bromine water.

Does phenol Decolourise bromine water?

Hint: When bromine water is added to a solution of phenol in water, the bromine water is decolourised and a white precipitate is formed which smells of antiseptic. We know that the reaction of phenol and water with bromine is known as bromination of phenol.

Can alkynes Decolourise bromine water?

Unsaturated hydrocarbons are much more volatile than the parent alkanes, including alkenes and alkynes. For example, they react easily with bromine to add a Br2 molecule across the double bond of C=C. The colour of Br2 easily disappears when combined with alkene or alkyne.

Does Cyclobutane Decolourise bromine water?

However, cycloalkanes do not decolourise bromine water because it consists of single carbon- carbon bonds which means that the molecule is saturated and it will show no reaction when cycloalkanes reacts with bromine water. The yellow colour of bromine remains as such.

What Colour is bromine?

reddish brown
Physical and chemical properties Free bromine is a reddish brown liquid with an appreciable vapour pressure at room temperature. Bromine vapour is amber in colour.

Which is of the following compounds decolourise bromine water?

Alkene decolorizes bromine water so it is often used as a test for unsaturated hydrocarbon. Perhaps the question needs more information. However, Bromine water de-colorization is a property of alkenes. Alkenes are a group of organic compounds that possess one or multiple pi bonds.

Is it possible to decolourise alkenes with bromine water?

No thats not possible, bromine water can only decolourise alkenes not carboxylic acids. Rep: ? You get these gems as you gain rep from other members for making good contributions and giving helpful advice. the C=O bond is nt broken at all.

Why does benzene not decolorize bromine water?

The decolorization of bromine water is an indication that the Br2 has reacted with something. Bromine “adds across” multiple bonds in alkenes and alkynes. Benzene does not have alternating double and single bonds (as Lewsi structures might imply).

Can a carboxylic acid be added to bromine water?

The nly bond affcted by bromine water is C=C because one of the bonds in there s pretty wek in comparison to the rest of the compound. Yes, technically, though it wouldn’t be the carboxyl group that was doing it. Propenoic acid, for example, would undergo addition of bromine across its C=C bond in the same manner as your commoner-garden alkenes.
