Reaction of alkene with bromine water
WebThe bromination reaction can be used to determine if an unknown hydrocarbon substance should be classed as an alkene or an alkane. 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. WebAlkene groups react with bromine water and perform an additional reaction, culminating in a decolourised solution, which occurs mainly in the dark. On the other hand, alkane does not interact with bromine water. Hence the colour of bromine water does not change.

Alkenes are unsaturated molecules, atoms can add to them via the C=C double bond, so a reaction occurs.. Alkenes readily react with halogens e.g. bromine, at room temperature and pressure. Bromine water is used in a simple test for unsaturated alkenes to distinguish …
WebFigure 10.3c Hydration reaction of alkene vs. dehydration reaction of alcohol. Addition of Alcohol to Alkenes. With the presence of acid, an alcohol can be added to the alkene in the same way that water can be, and ether is formed as a product. For example: Figure 10.3d Example of addition of Alcohol to Alkenes WebAn alkene does not react with pure water since water is not acidic enough to allow the hydrogen to act as an electrophile to start a reaction. However, with the presence of a …
WebThe reaction between 2-butene and bromine to form 2,3-dibromobutane is just one example of the addition reactions of alkenes and alkynes. Hydrogen bromide (HBr) adds across a C=C double bond to form the corresponding alkyl bromide, in which the hydrogen ends up on the carbon atom that had more hydrogen atoms to begin with.
