Ethanol does not react with bromine water because it lacks enough unsaturation or pi bonds in its molecular structure to undergo a bromination reaction. Bromine water typically reacts with compounds containing carbon-carbon double bonds (alkenes) or aromatic rings that can participate in electrophilic addition reactions with bromine. Ethanol, being a simple alcohol, does not possess these reactive sites for bromination to occur.

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.
Does hexane and bromine water and sodium hydroxide solution react?
Hexane and bromine water do not react with each other. However, sodium hydroxide solution can react with hexane through a process called saponification to form soap, but it does not react with bromine water.
Why does polyethene not react in the same way with bromine water as ethene?
Polyethylene is a polymer composed of many repeating ethylene units, which do not have a readily available double bond like ethene. Bromine water can react with double bonds through an addition reaction, but the absence of double bonds in polyethylene limits its reactivity towards bromine water.
What is the Reaction of salicylic acid with bromine water?
Salicylic acid does not react with bromine water under normal conditions. However, if heated, bromine may react with salicylic acid to form 2,3-dibromosalicylic acid.
What is seen when bromine water is shaken with an saturated fat?
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.
Does ethanol make bromine water go colorless?
Yes, ethanol can react with bromine water causing it to go colorless. The ethanol reduces the orange-brown bromine color to the colorless bromide ion.
What happens when ethanol reacts with bromine water?
When ethanol reacts with bromine water, the bromine is displaced by the oxygen in ethanol, resulting in decolorization of the bromine water. This reaction occurs because ethanol is a reducing agent, which means it can donate electrons to the bromine atoms, converting them from a colored form (brown/red) to a colorless form.
What are two tests distinguish between ethanol and phenol?
The ferric chloride test: Ethanol does not react with ferric chloride, while phenol forms a purple color when mixed with ferric chloride. The bromine water test: Ethanol does not react with bromine water, while phenol decolorizes bromine water due to its reducing properties.
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.
Does Bromine react with water?
no
Does hexane and bromine water and sodium hydroxide solution react?
Hexane and bromine water do not react with each other. However, sodium hydroxide solution can react with hexane through a process called saponification to form soap, but it does not react with bromine water.
How bromine react with water?
it blows up<---- hilar
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.
Does bromine water react with potassium chloride?
Yes, bromine water (Br2) will react with potassium chloride (KCl) to form potassium bromide (KBr) and chlorine gas (Cl2) as products. This reaction typically involves the displacement of bromine by chlorine in the compound.
How does bromine react with water?
Bromine reacts with water to form a mixture of hydrobromic acid (HBr) and hypobromous acid (HOBr) in an equilibrium reaction. The reaction is reversible, with bromine being both slightly soluble in water and able to react with it to form the acids.
Why does polyethene not react in the same way with bromine water as ethene?
Polyethylene is a polymer composed of many repeating ethylene units, which do not have a readily available double bond like ethene. Bromine water can react with double bonds through an addition reaction, but the absence of double bonds in polyethylene limits its reactivity towards bromine water.
When benzene reacts with bromine water will it decolourise bromine water or not?
Yes, benzene does not react with bromine water, so the bromine water will retain its reddish-brown color when benzene is added to it.
