No, unsaturated oils and fats (sunflower oil, olive oil) decolourise when reacted with bromine
When bromine water is shaken with a saturated fat, the bromine water will turn colorless. This is because saturated fats do not contain double bonds to react with the bromine in a typical alkene addition reaction, which would normally turn the bromine water brown/orange.
Bromine water will change from orange to colourless when it is mixed with saturated fat.
The reaction between phenol and bromine water results in the substitution of a hydrogen atom on the benzene ring with a bromine atom. This forms bromophenol as the product. The reaction is a bromination reaction and the presence of phenol's hydroxyl group activates the benzene ring towards electrophilic substitution.
Pentene is an unstaturdated hydrocarbon (One that does not have many possible side branches) It reacts readily with halogens to form new substances. In this case, bromine reacts with pentene in an addition reaction, this changes pentene into 1,1-dibromopentane. Thus, removing bromine from the solution, hence the distinct orange color is removed.
Classic question. And although many things would, you're probably wanting the answer "alkenes".This is because alkenes are unsaturated. They have a C=C double bond. Electrons just waiting to be taken.Bromine is a halogen. It's dying to get just one more electron to fill its octet, so Br2 will attack the C=C and take some electrons in the form of a covalent bond.Example:H2C=CH2 + Br2 ---> H2BrC-CBrH2Now each carbon has 4 bonds and Bromine has filled its octet. All's good.
Saturated hydrocarbon does not decolourise bromine water while unsaturated hydrocarbon decolourize it.
The purple KMnO4 is decolourise
Decolorization of bromine is more rapid with unsaturated compounds because they readily react to form brominated products. Saturated compounds are less reactive and decolorize bromine at a slower rate.
When bromine water is shaken with a saturated fat, the bromine water will turn colorless. This is because saturated fats do not contain double bonds to react with the bromine in a typical alkene addition reaction, which would normally turn the bromine water brown/orange.
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.
Bromine water will change from orange to colourless when it is mixed with saturated fat.
Oils contain both unsaturated and saturated fatty acids. See Related Links. Most oils are lower in saturated fatty acids than some solid shortenings or animal fats - except for the tropical oils.
olive and canola oils are examples of saturated fats
One simple test to distinguish between saturated and unsaturated compounds is the bromine water test. Saturated compounds do not react with bromine water (no color change), whereas unsaturated compounds will decolorize the bromine water due to addition of bromine across the double bond in the unsaturated compound.
Benzene will not decolourise bromine water as it does not undergo addition reaction. It is highly saturated due to presence electron cloud above and below it.
The definiton of saturated oils is oil in thongs and condoms!
The healthiest oils are oils that have polyunsaturated and monounsaturated fats. The healthiest oils are oils packed with saturated fats.
