What type of reaction do alkanes go through when exposed to bromine water?
Alkanes undergo a substitution reaction with halogens in the presence of light. For instance, in ultraviolet light , methane reacts with halogen molecules such as chlorine and bromine. This reaction is a substitution reaction because one of the hydrogen atoms from the methane is replaced by a bromine atom.
How does alkane react with bromine?
Alkanes are far less reactive than alkenes and will only react with bromine water in the presence of UV light. Under these conditions, alkanes undergo substitution reactions with halogens, and will slowly de-colourise bromine water.
When bromine water is used which would react alkane or alkene explain why?
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.
How do alkenes react with bromine water?
How bromine water can be used to distinguish between an alkane and an alkene?
You can use bromine water, which is an orange solution, to distinguish between alkanes and alkenes. There is no change when bromine water is mixed with an alkane, but it turns colourless when mixed with an alkene.
How does bromine water distinguish between alkanes and alkenes?
What colour does alkenes turn bromine water?
colourless
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene.
How does an alkane react with bromine?
Why does alkene react with bromine water?
Bromine water is used in a simple test for unsaturated alkenes to distinguish them from saturated alkanes. The pi bond of the double bond opens up and two new carbon – bromine bonds (C–Br) are formed. This double bond makes alkenes much more reactive than alkanes, the bromine water test for alkenes is just one example.
Does alkane react with bromine water?
AlkANE will react with bromine-water if u shine a Ultra-violet light on it, ask your school teacher (esp your phyics teacher) i’m sure they have a UV light…
How do you make bromine water?
Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br 2) in water (H 2 O). Bromine water solution can be prepared in the chemistry lab by direct mixing of fumes of bromine and water.
What is the molecular weight of bromine water?
The molecular weight of bromine water is 159.81 and the density is 1.307 g/mL. Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br 2) in water (H 2 O). Bromine water solution can be prepared in the chemistry lab by direct mixing of fumes of bromine and water.
What happens when ethene reacts with bromine water?
For example, ethene reacts with bromine water to give 1,2 dibromo ethanes. The reaction takes place at room temperature if the reactants are in the gaseous state (ethene).
