Do bromine water and hexane go clear in light or dark?
Bromine water will go clear in the dark, while hexane will not change color in either light or dark conditions.
What is a simple chemical test to distinguish between bezene and hexane answer?
One simple chemical test to distinguish between benzene and hexane is the Bromine test. Benzene will not react with bromine in the absence of a catalyst, while hexane will readily react with bromine to form a colorless product.
Which observations are made in the reaction of toulene with bromine water?
When toluene reacts with bromine water, it undergoes electrophilic aromatic substitution. The color of the bromine water fades from orange to colorless due to the addition of bromine to the aromatic ring of toluene, forming bromotoluene. This reaction is used to test for the presence of aromatic compounds.
What observations are made in the reaction of hexane and concentated sulphuric acid?
In the reaction of hexane with concentrated sulfuric acid, the acid acts as a dehydrating agent and can lead to the formation of alkyl sulfates and alkenes. The reaction may also produce some byproducts like water and sulfur dioxide gas. Heat is usually evolved during the reaction due to its exothermic nature.
Why does Br2 dissolve in cyclohexane and not in water?
Bromine (Br2) dissolves in cyclohexane due to its nonpolar nature, which is similar to cyclohexane's nonpolar composition. In contrast, bromine does not dissolve in water because water is a polar solvent and bromine is nonpolar, leading to poor solubility due to the mismatch in polarity.
Is bromine more soluble in hexane or in water?
Bromine is soluble in water.
Do bromine water and hexane go clear in light or dark?
Bromine water will go clear in the dark, while hexane will not change color in either light or dark conditions.

Does hexane and bromine water and sodium hydroxide solution react?
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.

How can remove the bromine from hexane solvent?
One method to remove bromine from a hexane solvent is through distillation. By heating the mixture to its boiling point, the hexane will vaporize while the bromine will remain behind, allowing for separation. Another method is to use a reducing agent like sodium thiosulfate, which can react with bromine to form a non-volatile compound that can be easily removed.
Why does Br2 dissolve in cyclohexane and not in water?

What happens when bromine water is shook up with propene?
When bromine water is shaken up with propene, the bromine water will decolorize due to the addition reaction between bromine and propene. This reaction results in the formation of a colorless 1,2-dibromoethane product.
What happens if ethene is shaken with bromine water?
If ethene is shaken with bromine water, the orange color of bromine water will be decolorized due to the addition reaction of bromine to ethene. This reaction results in the formation of a colorless compound called 1,2-dibromoethane.
What is the observed reaction when a substance is mixed with bromine water?
When a substance is mixed with bromine water, the observed reaction is the substance turning from its original color to a colorless or pale yellow solution. This indicates that the substance has reacted with the bromine water.
What happens when bromine water reacts with alkenes?
Bromine water reacts with alkenes through an electrophilic addition reaction where the pi bond of the alkene breaks, and bromine atoms are added to the carbon atoms. This reaction results in the decolorization of the bromine water, changing it from orange to colorless.
