Why the unsaturated compound decolourises with bromine?
Unsaturated compounds decolorize bromine because bromine is added across the double bond through an electrophilic addition reaction. This reaction converts the orange bromine solution to a colorless product, resulting in decolorization of the solution.
When benzene reacts with bromine water will it decolourise bromine water or not?
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
What happens when 1 drop of bromine is added to vegetable oil?
When 1 drop of bromine is added to vegetable oil, a chemical reaction occurs where the bromine reacts with the unsaturated fats in the oil. This reaction causes the bromine to decolorize, turning from reddish-brown to colorless. This change is a test for the presence of unsaturated fats in the vegetable oil.
Why bromine solution added gradually?
Bromine solution is added gradually to prevent a violent reaction due to the exothermic nature of the reaction between bromine and the target compound. Slow addition allows for better control and ensures safety.
A chemical reaction in which a double bond of an unsaturated compound is broken and atoms are added at the point where the bond is broken?
This type of reaction is known as an addition reaction. It involves the breaking of a double bond in an unsaturated compound and the addition of atoms or groups of atoms to the carbon atoms previously involved in the double bond. Addition reactions are common in organic chemistry and are used to introduce functional groups into molecules.
How bromine is used to test for unsaturation in organic compounds?
Bromine is used as a reagent to test for unsaturation in organic compounds due to its ability to react with alkenes and alkynes, which contain carbon-carbon double or triple bonds. When bromine is added to a saturated compound, no reaction occurs, and the reddish-brown color of bromine persists. However, if the compound is unsaturated, bromine will react with the double or triple bonds, resulting in a color change as the reddish-brown color disappears. This decolorization indicates the presence of unsaturation in the organic compound.
Why the unsaturated compound decolourises with bromine?
Unsaturated compounds decolorize bromine because bromine is added across the double bond through an electrophilic addition reaction. This reaction converts the orange bromine solution to a colorless product, resulting in decolorization of the solution.

What happens when bromine water is added to ethanol?
When bromine water is added to ethanol, the bromine will react with the ethanol forming 2-bromoethanol. The reaction occurs via nucleophilic substitution where the bromine reacts with the -OH group of ethanol. This reaction can be used as a test to distinguish between primary, secondary, and tertiary alcohols.
What substance is added to an organic molecule to test for the degree of saturation?
Bromine or potassium permanganate is added to an organic molecule to test for the degree of saturation. These reagents react differently with saturated and unsaturated compounds, producing distinct color changes or precipitates that can be used to identify the degree of saturation.
Give a test to differentiate between butter and cooking oil?
there can be two explanation: 1. cooking oil is unsaturated while butter is saturated so buter can not be hydrogenated but cooking oil can be. 2. as we know that brown colour of bromine disappears when a drop of bromine is added to unsaturated compound whereas there is no reaction between saturated hydrocarbons.
What happens when 1 drop of bromine is added to vegetable oil?
When 1 drop of bromine is added to vegetable oil, a chemical reaction occurs where the bromine reacts with the unsaturated fats in the oil. This reaction causes the bromine to decolorize, turning from reddish-brown to colorless. This change is a test for the presence of unsaturated fats in the vegetable oil.
What happens when bromine water is added to oil?
When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.
What will happen if water is added to organic compound?
If water is added to an organic compound, the compound can dissolve in water if it is soluble or form a separate layer if it is insoluble. In some cases, the compound may react with water to form a new compound.
What happens when bromine water is added to paraffin?
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
Color change when bromine water is added to cyclopentane hydrocarbon?
When bromine water is added to cyclopentane, there is no color change observed. This is because cyclopentane is a saturated hydrocarbon, lacking double or triple bonds that would allow for a reaction with bromine. The bromine water retains its reddish-brown color, indicating that no bromination has occurred. In contrast, unsaturated hydrocarbons would react, resulting in a decolorization of the bromine water.
What happens When is bromine is added to cyclohexane?
When bromine is added to cyclohexane, bromination of the cyclohexane molecule may occur. This involves the substitution of a hydrogen atom in the cyclohexane ring with a bromine atom. This reaction can result in the formation of a new compound with bromine substituents on the cyclohexane ring.
