Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.

What does the baeyers test indicate?

The Baeyer's test is often used to detect the presence of unsaturation in organic compounds, such as alkenes and alkynes. When a compound undergoes the Baeyer's test, it forms a colored product that can be used to confirm the presence of unsaturation.


What does bromine in chloroform test for?

Bromine in chloroform tests for the presence of unsaturation in a compound. It reacts with alkenes or alkynes to form red or brown coloration in the chloroform layer. This test is known as the bromine test.


What is the test used to determine the degree of unsaturation?

number of rings


Does ethyne decolourize KMnO4 solution?

Yes it does. This is a general test for unsaturation.

Is bromine water good for testing for unsaturation?

Yes, bromine water is commonly used to test for unsaturation in organic compounds. It reacts with double or triple bonds in unsaturated compounds, causing a color change from brown to colorless. This test is often used to distinguish between saturated and unsaturated hydrocarbons.


Why do you shake bromine water with chloroform?

Shaking bromine water with chloroform is a common test to detect the presence of unsaturation in a compound. If an alkene is present, it will react with bromine to decolorize the bromine water, forming a colorless solution due to the addition of bromine across the double bond. This test is known as the bromine test for unsaturation.


If you are doing the baeyer test and your solution stays purple what does that mean?

If your solution stays purple during the Baeyer test, it means that no unsaturation (such as carbon-carbon double or triple bonds) is present in the compound being tested. The purple color indicates a negative result for unsaturation.


What makes an alkene not an alkane?

unsaturation


What is the result when hexane undergoes baeyer's test?

If hexane undergoes Baeyer's test, it will not show any color change or form a precipitate. Baeyer's test is typically used to detect the presence of unsaturation in organic compounds, so since hexane is a saturated hydrocarbon, it will not react with the reagents in the test.


Why the colour of bromine fades when carrying unsaturation test?

Some of the bromine is consumed by forming dibromides from the unsaturated compounds tested. The dibromides do not usually have color, as bromine molecules do.


Do 1-methyl-1-cyclohexene and methylenecyclohexane differ from each other using any of the tests for unsaturation?

Yes, the two compounds differ in their reactivity to bromine water, a test for unsaturation. 1-methyl-1-cyclohexene would decolorize bromine water due to its alkene double bond, while methylenecyclohexane (1,1-cyclohexadiene) would not decolorize bromine water, as it lacks a double bond in its structure.
