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 compound decolourizes bromine water?
Unsaturated hydrocarbons such as alkenes and alkynes will decolourize bromine water.
What happens when ethanol reacts with bromine water?
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
Why does alkyne decolourise bromine water?
The alkyne reacts with bromine removing it from the aqueous solution.
What is bromine reaction with water?
Bromine reacts with water to form a mixture of Hydrobromic Acid, HBr, and Hypobromous Acid, HBrO.
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 compound decolourizes bromine water?
Unsaturated hydrocarbons such as alkenes and alkynes will decolourize bromine water.
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
Why does bromine water fade when testing for saturation?
Bromine reacts with the double / triple bonds giving typically a colourless compound. the bromine water therefore fades as the bromine reacts.
What happens when ethanol reacts with bromine water?
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
Why does alkyne decolourise bromine water?
The alkyne reacts with bromine removing it from the aqueous solution.
What happen when d-glucose reacts with bromine in water?
Bromine Water disappear thus forming Gluconic Acid
Why alkanes do not react with bromine water?
No, bromine will only add to alkenes, so NO addition reaction to alkanes. Subtitution on alkanes is not possible at standard conditions
What is bromine reaction with water?
Bromine reacts with water to form a mixture of Hydrobromic Acid, HBr, and Hypobromous Acid, HBrO.
What happens when bromine water is added to ethanol?
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
How bromine water can be used to test for an alkene?
Alkenes, or hydrocarbons with at least one double bond undergo an addition reaction when combined with bromine (Br2). The general reaction is H2C=CH2 --> H2BrC--CBrH2, and it occurs readily. This reaction is a good way to identify alkenes because bromine has a reddish color, while alkanes and alkenes are colorless. So if bromine is added to an unknown hydrocarbon, the disappearance of the color is an indication of the presence of a pi bond.
What are the Chemical equations to distinguish between alkane and alkene?
Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.
