Why is the reaction of ethene with bromine called an addition reaction?

Br2 + C2H4 → C2H4Br2 OR
Br2 + CH2=CH2 → BrCH2CH2Br
The name of the reaction is pretty intuitive. Ethene's double bond is broken which leaves room for bromine to be added to form dibromoethane.

Ethene reacts with water to form ethanol This type of raction is called?
Such reactions are known as HYDRATION and are performed in presence of sulphuric acid.
Why does polyethene not react in the same way with bromine water as ethene?
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
What is the reaction of ethene with bromine in aqueous solution of sodium chloride?
1,2 dibromoethane and 1-bromo, 2-chloro ethane and 2-bromo ethanol
Why is the reaction of ethene and chlorine not a free-radical addition reaction?
because no free radicals are involved in the reaction process only carbo cations and Cl- are evolved which are ionic !!!
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.

Which compounds take part in an addition reaction?
Ethene undergoes addition reaction

Why does bromine go clear after the addition of ethene?
Bromine is an electrophile (electron deficient species) it attacks the Carbon doubble bond and accepts a pair of electrons. this is known as electrophillic addition. the equation is: C2H4 + Br2 - C2H4Br2 the product is 1,2 dibromoethane. this product is colourless.
Why is the reaction of ethene and chlorine not a free-radical addition reaction?
because no free radicals are involved in the reaction process only carbo cations and Cl- are evolved which are ionic !!!
Which tets coudl be used to distinguish between ethene and methane?
Ethene can react with Bromine water - turns colourless
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
What happens when bromine water is added to ethanol?
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
What happens if ethene is shaken with bromine water?
The solution will turn the orange bromine water into a colourless solution
If ethene reacts with chlorine the only product is CH2 Cl-CH2Cl What type of reaction took place?
This is an addition reaction, as the double carbon-carbon bond in ethene breaks to accomodate the two chlorine atoms. Product is 1,2, dichloroethane
