C3H6Cl2-(над стрелкой 2KOH, H2O)---X1--(K2Cr2O7, H2SO4)--C2H5COOH--(Cl2, P-крас)----X2---(NaHCO3)--X3---C2H5Br2)---X4

Answer 1

c3h6cl2+2koh=ch3ch2coh+2kcl+h2o

3ch3ch2cooh+k2cr2o7+4h2so4=3ch3ch2cooh+k2so4+cr2(so4)3+4h2o

ch3ch2cooh+cl2=ch3ch(cl)cooh+hcl

ch3ch(cl)cooh+nahco3=ch3ch(cl)coona+h2o+co2

ch3ch(cl)coona+ch3ch2br=ch3ch(cl)cooch2ch3+nabr
