2)1-хлорпропан--->пропанол-1----пропен+Hcl----Х1+NaOH,H2o-----X2+Kmno4,H---X3 

3)С2Н5Он+Н2So4---X1+KMno4,H2o---x2+Hbr---X3----этин+H----x4

4)СH4---хлорметан+Na---X1-H2---X2+H2o?H3po4---X3+Cuo---X4 

1)5CH3OH+6KMnO4+9H2SO4=5CO2+6MnO4+3K2SO4+19H2O

CO2+Ca(OH)2=CaCO3+H2O

CaCO3+CO2+H2O=Ca(HCO3)2

2)CH3-CH2-CH2Cl+KOH=CH3-CH2-CH2OH+KCl

CH3-CH2-CH2OH(t)= CH3-CH=CH2+H2O

CH3-CH=CH2+HCl=CH3-CHCl-CH3

CH3-CHCl-CH3+NaOH=CH3-CHOH-CH3+NaCl

5CH3-CHOH-CH3+2KMnO4+3H2SO4=5CH3-CO-CH3+K2SO4+2MnSO4+8H2O

3)C2H5OH=C2H4+H2O

3C2H4+2KMnO4+4H2O=3 CH2OH-CH2OH+2MnO2+2KOH

CH2OH-CH2OH+2HBr=CH2Br-CH2Br+2H2O

CH2Br-CH2Br+CH=-CH = CH2=CH-C=-CH +2HBr

                                                 винилацетилен("Х4")

4)СH4+Cl2=CH3Cl+HCl

2CH3Cl+2Na=C2H6+2NaCl

C2H6=C2H4+H2

C2H4+H2O=C2H5OH

C2H5OH+CuO=C2H4O+Cu+H2O
