How can bromine water test the difference between alkanes and alkenes?
Bromine water can differentiate between alkanes and alkenes because alkenes can decolourize bromine water due to their ability to undergo addition reactions. Alkanes, being saturated hydrocarbons, do not react with bromine water because they lack double bonds to facilitate the addition reaction.
What are the Chemical equations to distinguish between alkane and alkene?
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.
Is there bromine water discoloration at reaction with aqueous solution?
Bromine water will change color in the presence of certain organic compounds, such as alkenes or phenols. When bromine water is added to an aqueous solution containing these compounds, the bromine will react with the double bonds in the alkenes or the aromatic rings in phenols, resulting in a color change from orange to colorless.
Which test is better combustion or bromine water when testing alkenes against alkane?
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.
What is the reagent to distinguish alkene and alkyne?
Bromine in water or bromine water can be used to distinguish between an alkene and an alkyne. Alkenes will decolorize bromine water by undergoing addition reactions, while alkynes will not react under normal conditions and will not decolorize bromine water.

What functional groups does bromine in chloroform test for?
Bromine in chloroform typically tests for the presence of alkenes or aromatic compounds. Bromine will react with the double bond or aromatic ring to form a dibromo compound, resulting in a color change from red-brown to colorless. This test is commonly known as the bromine test.

What is the color change between aqueous bromine and sodium chloride?
There will be no colour change between the two, as chlorine is more electronegative than bromine and will maintain its negative charge, meaning that the bromine will not react and the orange colour persists.
What is the reagent to distinguish alkene and alkyne?
Bromine in water or bromine water can be used to distinguish between an alkene and an alkyne. Alkenes will decolorize bromine water by undergoing addition reactions, while alkynes will not react under normal conditions and will not decolorize bromine water.
Why alkanes do not react with bromine water?
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.
Why does the bromine dissolved in carbon tetrachloride is not used to differentiate between alkenes and alyles?
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.
What happened when bromine water was shaken with the gas produced?
If the gas was hydrogen, it would have decolorized the bromine water, turning it from orange to colorless. This is a common test for the presence of unsaturated hydrocarbons like alkenes, which react with bromine to form colorless products.
What does bromine commonly react with?
Bromine commonly reacts with alkali metals, such as sodium, potassium, and magnesium, to form ionic compounds called metal bromides. It also reacts with alkenes to form dibromo compounds through addition reactions. Additionally, bromine can react with organic compounds to substitute hydrogen atoms with bromine atoms in a process called bromination.
Does bromine react vigorously?
Bromine is a reactive element and can react vigorously under certain conditions. It is known to undergo violent reactions with other substances such as metals, alkenes, and organic compounds. Special care must be taken when working with bromine to avoid accidental exposure or reactions.
