WebPart 6: Reactions as Chemical Tests For the following pairs of substances (i) draw their structures and (ii) describe a chemical test which can be used to distinguish between them (state any reactants/conditions required and explain the results of the test). a. cyclohexane and hex-2-ene (i) (ii) The addition of a few drops of bromine water to each will produce … WebFeb 13, 2024 · Ethene is an alkene and as such is unsaturated, meaning it has one carbon to carbon double bond. So they can be identified by their displayed formulae, as ethene has the double bond functional group. Chemically, they can be distinguished most easily by the reaction with bromine water, which is orange/red in colour.

WebThe old name for the alkanes was the paraffins. ? Alkynes may have one or more triple bonds in their structure. ? Alkanes are much more stable than alkenes because of the presence of the C=C double bond. ? The simplest aromatic compound is benzene. Ethene burns in oxygen to form carbon dioxide and water. WebThe reaction with bromine happens at room temperature. If you have a gaseous alkene like ethene, you can bubble it through either pure liquid bromine or a solution of bromine in an organic solvent like tetrachloromethane. The reddish-brown bromine is decolourised as it reacts with the alkene.
WebC=C, allows alkenes to undergo addition reactions. For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. WebAlkenes 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.
