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.
The addition of bromine to pentene typically follows the general equation: C5H10 + Br2 --> C5H10Br2. This reaction is an example of electrophilic addition where the bromine molecule is added across the carbon-carbon double bond in pentene.
Yes, saturated oils like coconut oil or palm oil will decolourize bromine because the double bonds in unsaturated oils are required for the bromine addition reaction that causes discolouration. Saturated oils lack these double bonds, so they will not react with bromine in the same way.
The reaction between 2-pentene and bromine is an addition reaction. The double bond in 2-pentene reacts with bromine to form a dibromoalkane. This reaction proceeds via an electrophilic addition mechanism.
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.
Bromine water fades when testing for saturation because the bromine is decolorized by the unsaturated organic compounds present in the solution. This reaction occurs because the unsaturated compounds react with and break the bromine-bromine bond, causing the bromine solution to lose its color.
The addition of bromine to pentene typically follows the general equation: C5H10 + Br2 --> C5H10Br2. This reaction is an example of electrophilic addition where the bromine molecule is added across the carbon-carbon double bond in pentene.
Pentene does not react with bromine at room temperature because it requires an initiation step, typically heat or light, to start the reaction. Without this activation energy, the carbon-carbon double bond in pentene remains stable and unreactive towards bromine.
The major product formed from the reaction of 1-pentene with bromine (Br2) is 1,2-dibromopentane. Bromine adds across the double bond, resulting in the addition of a bromine atom to each of the carbon atoms that were part of the double bond.
The purple KMnO4 is decolourise
Pentene (CH3CH2CH=CHCH3) reacts with bromine by undergoing an addition reaction. The equation would be: CH3CH2CH=CHCH3 + Br2 --> CH3CH2CHBrCHBrCH3
Alkynes can decolourize bromine water due to the addition reaction that occurs. The bromine molecules add across the carbon-carbon triple bond in the alkyne, forming a colorless dibromoalkane product. This reaction is specific to alkynes and does not occur with alkenes or alkanes.
Yes, saturated oils like coconut oil or palm oil will decolourize bromine because the double bonds in unsaturated oils are required for the bromine addition reaction that causes discolouration. Saturated oils lack these double bonds, so they will not react with bromine in the same way.

Saturated hydrocarbon does not decolourise bromine water while unsaturated hydrocarbon decolourize it.
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 is a dilute solution of bromine that is normally orange-brown in colour, but becomes colourless when shaken with an alkene. Alkenes can decolourise bromine water, while alkanes cannot.
2 percent bromine solution typically has a reddish-brown color.
