What is the reaction between methane and bromine?
When a mixture of methane and bromine is exposed to ultraviolet light – typically sunlight – a substitution reaction occurs and the organic product is bromomethane. However, the reaction doesn’t stop there, and all the hydrogens in the methane can in turn be replaced by bromine atoms.
What happens when bromine water is added to ethane?
Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction is known as electrophilic addition.
What conditions are needed for the reaction between ethane and bromine to take place?
In the presence of UV light, ethane will react with bromine in a substitution reaction. UV light is the condition under which the reaction will occur so it is written above the arrow in the chemical equation.
What type of reaction is ethene and bromine?
Explanation: Ethene and bromine are an addition reaction because ethene is an alkene – it has a double bond. It is easier for new atoms to open the double bond and react there than to remove the hydrogen already attached, and then bond to it, which would be a substitution reaction.
What type of reaction is ethene bromine?
What is the reaction of ethene and bromine water?
In the case of the reaction with ethene, 1,2-dibromoethane is formed. This decolourisation of bromine is often used as a test for a carbon-carbon double bond. If an aqueous solution of bromine is used (“bromine water”), you get a mixture of products.
How can you identify ethane from ethene?
Ethane is an alkane and as such is saturated, Ethene is an alkene and as such is unsaturated. Chemicaly we can identify by adding bromine water to both alkane and alkene. In which ever cause colour changes that compound is ethene (alkene). Was this answer helpful?
What happens when bromine is added to ethene?
Two bromine atoms are attached to the two carbon atoms in the ethene molecule. This reaction can be done at room temperature or below temperatures than room temperature. Addition of bromine to ethene is an electrophilic addition reaction. Normally, bromine molecule (Br 2) is not electron deficiency compound.
What is the balanced equation for ethane and bromine?
The balanced equation of ethane and bromine is (by double displacement): C2H6 + Br2 –> C2H5Br + HBr What is the equation for the reaction between ethane and bromine?
What is the mechanism of ethene and propene with Br2 (L)?
Mechanism of ethene and propene with Br 2 (l) are explained also. Ethene is a symmetric alkene molecule. Ethene reacts with liquid bromine to give 1,2-dibromoethane. Ethene and bromine reaction also gives a symmetrical alkyl halide compound. Two bromine atoms are attached to the two carbon atoms in the ethene molecule.
Why is bromination faster than protonation of ethene?
A more stable transition state for the reaction with bromine means that bromination is the faster reaction. (In this particular case, water is such a weak Brønsted acid that it will never protonate ethene, no matter how long you wait. So there’s also that.)
