10.4 Reactions of Alkenes: Addition of Bromine and Chlorine to Alkenes An addition reaction also easily occurs between halogens (Br2and Cl2) and alkenes. In the presence of aprotic solvent, the product is a vicinal dihalide, as shown here for the addition of chlorine to propene. Figure 10.4a Addition reaction

Dissolve 1.0 g of the compound in 10-15 ml of glacial acetic acid, cautiously add a solution of 3-4 ml of liquid bromine in 10-15 ml of glacial acetic acid until the colour of bromine persists and allow the mixture to stand for 15-20 minutes. Pour into 50-100 ml of water, filter off the bromo compound at the pump and wash with a little cold water.

The reaction between an alkene and bromine involves the breaking open of the alkene's double bond and the inclusion of bromine in its structure (an addition reaction). This results in the production of an alkane with two …

 · The electron rich part of the double bond causes a dipole to form meaning that bromine becomes electron deficient and therefore becomes the electrophile (hence electrophillic addition). The double bond attacks the bromine and forms a new carbon – bromine bond, while the other carbon atom becomes electron deficient.

 · UNSATURATION TEST (BROMINE WATER TEST) Test for: Test for unsaturation of lipids Positive Visual Result: Colorless solution Principle: The presence of unsaturation in a fatty acids or a triglycerol can be detected by reaction with bromine.

2  · The electrophilic addition of bromine to ethene The facts Alkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown colour to give a colourless liquid.

When bromine water is added to an alkane, it will remain as an orange solution as alkanes do not have double carbon bonds (C=C) so the bromine remains in solution But when bromine water is added to an alkene, the bromine atoms add across the C=C bond, hence the solution no longer contains free bromine so it loses its colour Exam Tip
