What happens when bromine water is shook up with propene?
When bromine water is shaken up with propene, the bromine water will decolorize due to the addition reaction between bromine and propene. This reaction results in the formation of a colorless 1,2-dibromoethane product.
What colour change occurs when propene is added in bromine water?
Bromine water is originally orange-brown in color. When propene is added to bromine water, the orange-brown color fades as the bromine molecules react with the carbon-carbon double bond in propene. This reaction leads to the decolorization of the bromine water to a colorless solution.
What does propene and br2 equal?
Propene (C3H6) reacts with bromine (Br2) to form 1,2-dibromopropane when exposed to light. The addition of bromine to the double bond of propene causes the bromine atoms to be added across the double bond, resulting in a color change from orange to colorless as the reaction proceeds.
What is the observation between bromine and propene?
Bromine water is a dilute solution of bromine that is normally orange-brown in colour, but becomes colourless when shaken with an alkene. Alkenes can decolourise bromine water, while alkanes cannot.
How is propene converted into 1-bromopropane and 2- bromopropane?
Propene can be converted into 1-bromopropane by reacting it with hydrobromic acid in the presence of a peroxide initiator. The peroxide initiates a free radical chain reaction that leads to bromination of the propene. To form 2-bromopropane, propene can be treated with elemental bromine or N-bromosuccinimide (NBS) in the presence of light or heat, which leads to anti-Markovnikov addition of bromine across the alkene double bond.

Can you list 10 combustible materials?
wood, leaves, paper, wax, hydrogen gas, ethanol, methane, propane, propene, benzene (Propane and and propene are two different substances- propene has an extra double bond.)

What chemical tests can be used to distinguish between polymer and propene?
Propene is an alkene, whereas propane is an alkane. Thus, propene is an unsaturated molecule, having a carbon-carbon double bond. If you add bromine water, an aqueous solution of bromine, to the test tubes, you can tell which is propene, the alkene. The bromine reacts with and saturates the double bonds in alkenes, and so decolourises. The bromine does not decolourise when added to an alkane as it does not react. So, in conclusion:Add bromine water (brown) to the test tubesIf the bromine water stays brown, the test tube contains propaneIf the bromine water goes colourless, the test tube contained propene.
How man carbons does propene have?
Propene has 3 carbon atoms.
The formula for propane and propene?
Propane is C3H8.Propene is C3H6.
What is the major product from the treatment of propene with HCL?
The major product from the treatment of propene with HCl is 2-chloropropane. The HCl adds across the double bond of propene to form a secondary alkyl halide.
What is the propene formula?
The formula for propene is c3h6 the formula for propyne is c3h4.
If an alkene has three carbon atoms what is it called?
A three-carbon alkene is called propene.
