Answer 1

Answer:

Ethane & ethane - (C2H6) is nothing but same If you mean difference between ethane (alkane) and ethene (alkene). Then, addition of bromine water to both alkane and alkene. In which ever case colour changes that compound is ethene (alkene). Ethane : CH₃ - CH₃ Ethene : CH₂ =CH₂ CH₃ - CH₃ + Br₂ → no reaction : no colour change CH₂ =CH₂ + Br₂ → CH₂(Br) - CH₂(Br) : colour change
