1.When ethyl alcohol is heated strongly with mixture of red phsphorus and bromine,ethyl bromde is obtained.
3CH₃CH₂OH+PBr₃—red-P>3CH₃CH₂Br+H₃PO₃
2.When ethane is reacted with bromine in presence of AlBr₃,ethyl bromide is obtained.
CH₃-CH₃ + Br₂—-AlBr₃—> CH₃-CH₂-Br + HBr
3.Ethene or Ethylene can be used along with Hydrogen bromide solution to obtain ethyl bromide. It is an addition hydrohalogenation reaction, where reaction with the hydrogen bromide solution (an electrophile) attacks the C=C bond.
C₂H₄ + HBr → C₂H₅Br
