Why does polyethene not react in the same way with bromine water as ethene?
Oh, dude, it's like this - polyethene is like the chill, laid-back version of ethene. It's already in a stable, happy relationship with itself, so it's not looking to get involved with bromine water drama. Ethene, on the other hand, is out there on the prowl, ready to react and cause a scene. So yeah, polyethene's just like, "No thanks, bromine water, I'm good."
Does pentane react with bromine water?
Yes, pentane can react with bromine water. In the presence of UV light, pentane can undergo a substitution reaction with bromine water where one or more hydrogen atoms are replaced by bromine atoms. This reaction can occur slowly at room temperature but is accelerated with the presence of UV light.
Why bromine does not react with aqueous potassium chloride?
Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.
What happens when bromine water is added to ethanol?
When bromine water is added to ethanol, the bromine will react with the ethanol forming 2-bromoethanol. The reaction occurs via nucleophilic substitution where the bromine reacts with the -OH group of ethanol. This reaction can be used as a test to distinguish between primary, secondary, and tertiary alcohols.
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.
What test is used to show that ethene is unsaturated?
Bromine water test is used to show that ethene is unsaturated. In the presence of ethene, the red-brown color of bromine water disappears due to addition reaction with ethene, indicating its unsaturation.
Can ethene and bromine react without sunlight?
Yes, ethene and bromine can react without sunlight. The reaction occurs through an electrophilic addition mechanism, where bromine adds across the double bond of ethene to form 1,2-dibromoethane. This reaction can proceed in the dark, typically in a non-polar solvent, and is driven by the reactivity of the bromine molecule with the double bond of ethene.
How can you distinguish between ethene and ethyne by means of a chemical reaction?
One way to distinguish between ethene and ethyne is by performing a bromine water test. Ethene will decolorize bromine water, turning it from orange to colorless, while ethyne will not react with bromine water. This test takes advantage of the unsaturation in ethene that allows it to quickly react with bromine.
Which tets coudl be used to distinguish between ethene and methane?
Ethene can react with Bromine water - turns colourless

Can methane and bromine react without sunlight?
Methane and bromine cannot react without the presence of sunlight or U.V light because of lack of energy which is usually supplied by the U.V light to break the bromine molecules to free radicals for the reaction to occur.Hope my answer helped.ABUAD
Do ester react with bromine?
Yes, esters can react with bromine in the presence of a Lewis acid catalyst to undergo electrophilic aromatic substitution, resulting in the addition of bromine atoms to the ester molecule. This reaction is known as the Hunsdiecker reaction.
Does Hexane react with Bromine in the absence of ultraviolet light of intense heating?
No, hexane does not react with bromine in the absence of ultraviolet light or intense heating. Bromine typically requires the presence of such conditions to undergo a reaction with alkanes like hexane.
What information is needed to distinguish ethene from cyclohexane?
To distinguish ethene from cyclohexane, one can assess their physical properties and reactivity. Ethene is an unsaturated hydrocarbon with a double bond, making it reactive with bromine water, which will decolorize upon contact, whereas cyclohexane, a saturated hydrocarbon, will not react in this way. Additionally, ethene is a gas at room temperature, while cyclohexane is a liquid, providing another means of differentiation.
Does pentane react with bromine water?
Yes, pentane can react with bromine water. In the presence of UV light, pentane can undergo a substitution reaction with bromine water where one or more hydrogen atoms are replaced by bromine atoms. This reaction can occur slowly at room temperature but is accelerated with the presence of UV light.
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.
Why bromine does not react with aqueous potassium chloride?
Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.
