Complete answer: The reaction between alkene and bromine water is an example of electrophilic addition. Bromine has ionic properties: $\left( \text{B}{{\text{r}}^{-}} \right)$. Due to this property the bromine induces charges in pi-bond also. graphic advantage

alkanes and cycloalkanes with chlorine or bromine - chemguide

WebThe general formula for alkene is CnH2n. Alkenes are insoluble in water but are soluble in orgainic solvent. The presence of double bond between carbon-carbon atoms is a strong link. However, the second pi bond which is not as strong as the first sigma bond is more vulnerable to attack by suitable reagent, causing alkene to become relatively ... WebAlkenes undergo a number of other reactions, such as hydroboration, permanganate oxidation, and ozonolysis. Triple bonds are linear and the carbons are sp-hybridized (Figure 3). Alkynes, like alkenes, undergo addition reactions. A hydrogen connected to a triply bonded carbon is weakly graphicad ltdWebThe bromine water test is used to assess if an alkene or alkyne does have an unsaturated carbon-carbon bond. The test employs an addition reaction, in which a reactant, in this case, bromine, is introduced to an organic molecule in a way to destroy a double or triple bond. Bromine has an orange-brownish hue in the solution. graphic advance organizer
