Does ethene change from orange to colourless when it reacts with bromine water?
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
Does ethene react with Bromine in the presence of UV light?
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
What is the reaction of ethene with bromine in aqueous solution of sodium chloride?
When ethene reacts with bromine in an aqueous solution of sodium chloride, the bromine adds across the carbon-carbon double bond in ethene through electrophilic addition. This reaction forms a dibromoethane product. The presence of sodium chloride in the aqueous solution helps to generate hypobromous acid, which is the active bromine species that reacts with ethene. This reaction is an example of halogenation of alkenes.
Ethene reacts with water to form ethanol This type of raction is called?
Such reactions are known as HYDRATION and are performed in presence of sulphuric acid.
Why is the reaction of ethene and chlorine not a free-radical addition reaction?
The reaction of ethene and chlorine is not a free-radical addition reaction because it proceeds via an electrophilic addition mechanism. The π electrons of ethene attack the electrophilic chlorine molecule, leading to the formation of a cyclic intermediate called a chloronium ion. This is followed by the attack of a chloride ion to give the final product.
Why is the reason of ethene with bromine called an addition reaction?
The reaction of ethene with bromine is called an addition reaction because the bromine atoms add across the double bond of ethene to form a single product molecule. The double bond in ethene breaks and new single bonds are formed with bromine, resulting in an overall increase in the number of atoms in the product compared to the reactants. This type of reaction is characteristic of addition reactions where atoms or groups are added to a double or triple bond.
What happens if ethene is shaken with bromine water?
If ethene is shaken with bromine water, the orange color of bromine water will be decolorized due to the addition reaction of bromine to ethene. This reaction results in the formation of a colorless compound called 1,2-dibromoethane.
What happens when ethene is mixed with bromine water?
it goes from a browny orange to colourless
Why the reaction of ethene with bromine called an addition reaction?
Br2 + C2H4 → C2H4Br2 ORBr2 + CH2=CH2 → BrCH2CH2BrThe name of the reaction is pretty intuitive. Ethene's double bond is broken which leaves room for bromine to be added to form dibromoethane.
Is the reaction of ethene with bromine a redox reaction?
The reaction of ethene with bromine is not a redox reaction; it is an example of an electrophilic addition reaction. In this reaction, bromine adds across the double bond of ethene, resulting in the formation of dibromoethane. There is no change in the oxidation states of the elements involved, as both carbon and bromine retain their oxidation states throughout the process. Therefore, the reaction does not involve oxidation or reduction.
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.
Why does bromine go clear after the addition of ethene?
Bromine is an electrophile (electron deficient species) it attacks the Carbon doubble bond and accepts a pair of electrons. this is known as electrophillic addition. the equation is: C2H4 + Br2 - C2H4Br2 the product is 1,2 dibromoethane. this product is colourless.
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.
Does ethene change from orange to colourless when it reacts with bromine water?
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
Does ethene react with Bromine in the presence of UV light?
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.

This reaction forms a dibromoethane product. The presence of sodium chloride in the aqueous solution helps to generate hypobromous acid, which is the active bromine species that reacts with ethene. This reaction is an example of halogenation of alkenes.
What is observed when ethene is passed through bromine solution in carbon tetrachloride?
When ethene is passed through bromine solution in carbon tetrachloride, the initially red-brown color of the bromine solution decolorizes due to the addition of bromine across the carbon-carbon double bond in ethene, forming a colorless 1,2-dibromoethane product.
