How would you convert :
(a) ethene into 1, 2-dibromoethane?
(b) ethene into ethyl bromide?
(a) Ethene into 1, 2 -dibromoethane: Ethene reacts with bromine at room temperature to form saturated ethylene chloride.
CH2=CH2+Br2⟶Br|CH2−Br|CH21,2-dibromo ethane
(b) Ethene into ethyl bromide: When ethene is treated with HBr bromoethane is formed.
CH2=CH2+HBr⟶CH3−Br|CH2Ethyl bromide
