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.
Will decane give positive bromine test?
Positive Bromine tests are for unsaturated compounds that have double or triple bonds. Decane has a single bond, so the test will be negative.
What is the Reaction of salicylic acid with bromine water?
2,4,6-tribromophenol is formed by the loss of CO2 (decarbonylation).
What is seen when bromine water is shaken with an saturated fat?
When bromine water is shaken with a saturated fat, the bromine water will turn colorless. This is because saturated fats do not contain double bonds to react with the bromine in a typical alkene addition reaction, which would normally turn the bromine water brown/orange.
Why does bromine water fade when testing for saturation?
Bromine water fades when testing for saturation because the bromine is decolorized by the unsaturated organic compounds present in the solution. This reaction occurs because the unsaturated compounds react with and break the bromine-bromine bond, causing the bromine solution to lose its color.
How can bromine water test the difference between alkanes and alkenes?
Bromine water can differentiate between alkanes and alkenes because alkenes can decolourize bromine water due to their ability to undergo addition reactions. Alkanes, being saturated hydrocarbons, do not react with bromine water because they lack double bonds to facilitate the addition reaction.
Which test is better combustion or bromine water when testing alkenes against alkane?
The bromine water test is better for distinguishing between alkenes and alkanes. Alkenes decolorize bromine water due to their double bonds, forming a colorless solution, while alkanes do not react with bromine water. Combustion tests are not specific to alkenes and alkanes as both types of hydrocarbons will readily combust in the presence of oxygen.
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.
Does Bromine react with water?
no

Under what conditions do alkanes and benzene react with halogens?
Alkanes react with halogens (e.g. chlorine or bromine) only in the presence of UV light or heat to form halogenated products. Benzene does not readily react with halogens like alkanes do due to its aromatic stability, but it can undergo halogenation in the presence of a Lewis acid catalyst.
How bromine react with water?
it blows up<---- hilar
What happens when bromine water is shook up with propane?
When bromine water is shaken up with propane, a reaction occurs where the bromine water decolorizes. This is because bromine water is a reddish-brown color and reacts with the unsaturated bonds in propane to form colorless products. The reaction is a test for unsaturation in organic compounds, as alkenes and alkynes can react with bromine water to form colorless compounds, while alkanes do not undergo this reaction and the color of the bromine water remains unchanged.
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 is the reagent to distinguish alkene and alkyne?
Bromine in water or bromine water can be used to distinguish between an alkene and an alkyne. Alkenes will decolorize bromine water by undergoing addition reactions, while alkynes will not react under normal conditions and will not decolorize bromine water.
Does bromine water react with potassium chloride?
Yes, bromine water (Br2) will react with potassium chloride (KCl) to form potassium bromide (KBr) and chlorine gas (Cl2) as products. This reaction typically involves the displacement of bromine by chlorine in the compound.
How does bromine react with water?
Bromine reacts with water to form a mixture of hydrobromic acid (HBr) and hypobromous acid (HOBr) in an equilibrium reaction. The reaction is reversible, with bromine being both slightly soluble in water and able to react with it to form the acids.
