What happens when hexane reacts with bromine water?
What happens when hexane reacts with bromine water?
End result of the reaction of bromine water (Br2) with hexane (C6H14, an alkane) in a test tube (centre). This is a substitution reaction, where one bromine atom replaces a hydrogen atom in the hexane, forming bromohexane (C6H13Br) and hydrogen bromide (HBr).
Is hexane soluble in bromine water?
Usually HBr and H20. Your bromine preparation did not mix with either hexane or toluene because of their non-polar nature. They are non-miscible with water.
How does cyclohexane react with bromine water?
Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. A small amount of the ortho substituted product is also obtained from the bromination of anisole.
Does hexane dissolve in bromine?
This means that the electrons in the bond will be equally shared between the two bromine atoms. Thus, the molecule of bromine is nonpolar. Therefore, the statement that describes bromine dissolving in hexane is answer choice (D), a nonpolar substance dissolving in a nonpolar solvent.
Does benzene Decolourise bromine water?
Benzene does not decolourise bromine water.
What is the color of bromine in hexane?
| Halogen | Color in water | Color in hexane |
|---|---|---|
| Cl2 | pale, yellow green | yellow green (not orange) |
| Br2 | reddish | reddish or yellowish orange |
| I2 | colorless to violet | violet (pinkish) |
What kind of reaction does bromine water have with hexane?
Bromine water is orangish red in colour when ever it is made to react with unsaturated compound the colour of bromine disappers. It doesnot react with saturated hydrocarbons (compound having single bond) Now coming to your question, hexane will show no reaction with bromine water.
What happens when bromine is added to alkanes?
Bromine water added to hexane, cyclohexane and cyclohexene to show the difference in reactivity of alkanes and alkenes. This reaction demonstrates the Bromin…
What is the chemical equation for the reaction of hexene?
The chemical formula of 3-methyl-2-hexene is C7H14. Why does bromine react with hexene but not benzene? Adding halogens to alkene groups (X2) requires that the product adopt an anti configuration. Hexene will also lose its double bond upon bromination. Benzene is energetically unfavorable when a reaction attempts to break its double bond.
Why is bromine water used as a reagent?
Generally, bromine water is used as a reagent to test unsaturation in aliphatic compounds. So, when bromine water is treated with alkanes, which are saturated (such as hexane), it do not react and a clear layer of interface between alkane and bromine water is observed.
