The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.
Isopropyl alcohol is made from propene and water.
bromine water can be used to test whether the compund is saturated or unsaturated.
A simple test can be done to differentiate an alkene from an alkane using bromine water which has an orange/brown color. Adding alkanes to dilute bromine water will not result in a change of color, adding aklenes will cause the water to go clear.
water is 0% orange, but the % of water in an orange is 52.7652%
The solution will turn the orange bromine water into a colourless solution
Propene is an alkene, whereas propane is an alkane. Thus, propene is an unsaturated molecule, having a carbon-carbon double bond. If you add bromine water, an aqueous solution of bromine, to the test tubes, you can tell which is propene, the alkene. The bromine reacts with and saturates the double bonds in alkenes, and so decolourises. The bromine does not decolourise when added to an alkane as it does not react. So, in conclusion:Add bromine water (brown) to the test tubesIf the bromine water stays brown, the test tube contains propaneIf the bromine water goes colourless, the test tube contained propene.
a colourless solution
it turns to bacon :)
i think the unsaturated fat decolourises it :/
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
Propene is not soluble in water.
Yes, bromine water tests for double bonds and if they are present (like in an alkane such as ethane) it will change from orange/yellow to colourless.
i don't think that any change occurs, it remains the same
The bromine water turns from orange to colourless, as it is breaking the double bonds. When the oil becomes saturated, any more bromine water that is added will not turn colourless.
The ethene reacts with the bromine and the solution turns colourless (from its original orange colour).
it goes from a browny orange to colourless
