How do alkenes react with bromine water? | Socratic
They give the halohydrin, RCH(OH)CH_2Br, as the major product. The reaction of RCH=CH_2 with bromine water, Br_2(aq), illustrates the mechanism of electrophilic addition. The bromine molecule is polarizable, and is conceived to form a ""^(delta+)Br-Br^(delta+) intermediate, whose positive terminus acts as the electrophile. …

Bromine treatments are more complex than chlorine and can take longer to dissolve in water. Chlorine treatments are easier to apply and go into effect quicker. Chlorine dissolves faster in water below 75° F than bromine. Initials costs of bromine are higher compared to chlorine, but will be recouped over time (lower number of annual treatments).

Alkenes decolourise bromine water. The chemistry of the test. This is complicated by the fact that the major product isn't 1,2-dibromoethane. The water also gets involved in ...
Question #57f2d | Socratic
Here's how two solutions, one containing an alkane and the other an alkene, look like after the addition of bromine water. The test tube on the right contained an alkene, the one on the left an alkane. Answer link. Bromine water is simply a dilute solution of bromine. Bromine water contains bromine molecules, Br_2, dissolved in water.
Lesson Explainer: Addition Reactions of Alkenes | Nagwa
The bromine water will retain its characteristic orange color if the hydrocarbon is an alkane, and it will lose its characteristic orange color if the hydrocarbon is an alkene. The following reaction equation shows how the bromination reaction can be used to convert an ethene reactant into a 1,2-dibromoethane product: An example of the ...
25.16: Addition Reactions
Addition Reactions. An addition reaction is a reaction in which an atom or molecule is added to an unsaturated molecule, making a single product. An addition reaction can be thought of as adding a molecule across the double bond or triple bond of an alkene or alkyne. Addition reactions are useful ways to introduce a new functional …

Bromine Hot Tub Maintenance 101 (With Video)
Add your bromine floater. Retest your water weekly and refill your floater once a week with a few bromine tablets. Once a week, add non-chlorine or chlorine shock, depending on how your water looks and how often you use your hot tub. Chlorine shock will clear up murky water and quickly kill bacteria and contaminants.
phenylamine (aniline) and bromine water
This page looks at the reaction of the benzene ring in phenylamine (aniline) with bromine water. It explains why the amino group activates the ring. The -NH 2 group attached to the benzene ring in phenylamine has the effect of making the ring much more reactive than it would otherwise be. This is exactly the same as the effect of the -OH group ...
Achieving a Safe Bromine Level for Your Hot Tub Water
Run the hot tub, and wait a while to let your water mix and settle (the exact wait time will depend on water volume, amount of bromine in the spa, and the power/capacity of your pump). Then, test the water again. If testing shows the bromine level is still too high, repeat the process. You can also lower the bromine level by …
Bromine Water Test (Saturation Test)
Bromine water, often called the bromide bromate solution of bromine water, is a compound with the chemical formula Br 2. Bromine water does have a density of 1.307 g/mL and a molar size of 159.81. Bromine water seems to be a yellow mixed solution with a high oxidation capacity created by mixing diatomic bromine (Br 2) with water (H 2 O ...
inorganic chemistry
Bromine water is a reagent which is used to test for unsaturation in organic compound. It is $2.8~%$ bromine in water. In many places, it is refer to as bromine solution. But it is observed that adding bromine to water gives hypobromous acid ($ce{HOBr}$) and hydrobromic acid ($ce{HBr}$) via a disproportionation reaction.
