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.
What else can I help you with?
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 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 H2S Br2-----2HBr S redox reaction?
Yes, the reaction H₂S + Br₂ → 2HBr is a redox reaction. In this process, hydrogen sulfide (H₂S) is oxidized to sulfur (S) while bromine (Br₂) is reduced to bromide ions (Br⁻). The transfer of electrons between the reactants indicates that oxidation and reduction are occurring, characteristic of redox reactions.
Is browning banana a redox reaction?
A browning banana is a redox reaction.
How can a galvanic cell become an electrolytic?
the redox reaction is reserved
What happens when ethene is mixed with bromine water?
it goes from a browny orange to colourless
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.
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 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.
Why is 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.
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.
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.
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.
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.
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 is aluminum plus bromine?
When aluminum reacts with bromine, they form aluminum bromide, which is a white solid compound with the chemical formula AlBr3. This reaction is a redox reaction where aluminum loses electrons to bromine.
