Question

Этан-->(Pt, t)-->X1--->(H2O, H+)-->X2-->(HBr)-->X3-->(C6H6, AlCl3)--> этилбензол-->(H2SO4, KMnO4)-->X4

помогите решить цепочку

Answer 1

C2H6-----(Pt;t)----->C2H4+H2;

C2H4+H2O----->C2H5OH

C2H5OH+HBr----->C2H5Br+H2O;

C2H5Br+C6H6-----(AlCl3)----->C6H5C2H5+HBr;

5C6H5C2H5+18H2SO4+12KMnO4------>5C6H5COOH+5CO2+6K2SO4+12MnSO4+28H2O;
