प्रश्न
Ethylene (ethene), when reacts with halogens (chlorine and bromine) form saturated products. Name them and write balanced equations.
उत्तर
Chlorine and bromine are added to the double bond of ethene to form saturated ethylene chloride and ethylene bromide, respectively.
CH2 = CH2 + Cl2 → CH2(Cl) - CH2(Cl)
1,2-dichloro ethane
CH2 = CH2 + Br2 → CH2(Br) - CH2(Br)
1,2-dibromo ethane
