Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
The bromine water test is better for distinguishing between alkenes and alkanes. Alkenes decolorize bromine water due to their double bonds, forming a colorless solution, while alkanes do not react with bromine water. Combustion tests are not specific to alkenes and alkanes as both types of hydrocarbons will readily combust in the presence of oxygen.
Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.
Bromine dissolved in carbon tetrachloride is not typically used to differentiate between alkenes and alkynes because both alkenes and alkynes react with bromine under mild conditions, leading to addition reactions and forming dibromo compounds. This reaction does not provide a clear distinction between the two types of compounds. Other reagents, such as potassium permanganate or ozone, are more commonly used for distinguishing between alkenes and alkynes based on their respective chemical reactivity.
Organic compounds called Alkenes turns Bromine to colourless from orange-ish without sunlight as a catalyst. Alkanes however require sunlight to react.
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.

Alkanes do not react with bromine water because alkanes are saturated hydrocarbons, meaning they have only single bonds between carbon atoms. This makes them relatively unreactive towards electrophilic addition reactions, such as the reaction with bromine water. bromine water reacts with alkenes, which have carbon-carbon double bonds, through an electrophilic addition reaction.
The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.

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.
Bromine water can be used to test for an alkene by adding it to the alkene. The alkene will decolorize the orange-brown bromine water, turning it colorless, due to the addition of bromine across the carbon-carbon double bond in the alkene molecule. This reaction tests for the presence of unsaturation in the compound.
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.
1)Bromine solution in carbontetrachloride is used to identify alkanes, alkenes and alkynes. alkanes don't react therefore the color remains as it is ie, brown while alkenes and alkynes react and therfore brown color disappears. 2)Ammoniacal cuprous chloride when reacted with alkanes alkenes give no precipitate while with alkynes give red precipitate. Thus, alkanes with no reaction and unsaturation can be identified from the first test while alkynes from second test. combustion test solubility test kmno4 test sulfuric acid test
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.
