Answer 1

В
1)CH4+Cl2->CH3Cl+HCl
CH3Cl+Na->C2H6+NaCl(реакция Вюрца)
2)C2H6+Cl2->C2H5Cl+HCl
3)C2H5Cl+NaOH->C2H5OH+NaCl
4)2C2H5OH(кат.)->CH3=CH-CH=CH3+H2+2H2O
Г
1)CO+H2O<->CO2+H2
СO2+3H2<->CH3OH+H2O
2)CH3OH+HBr->CH3Br+H2O
3)2CH3Br+2Na->C2H6+2NaBr
4)C2H6+Cl2->C2H5Cl+HCl
5)C2H5Cl+NaOH->C2H5OH+NaCl
Д
1)CH4+Cl2(в присутствии освещения)->CH3Cl+HCl
2)2CH3Cl+2Na->C2H6+2NaCl
3)C2H6(t,кат.)->C2H4+H2
4)C2H4+HBr->C2H5Br
C2H5Br+NaOH->C2H5OH+NaBr
Е
1)C2H6(t,кат.)->C2H4+H2
C2H4+H2O(t,H2SO4)->C2H5OH
2)2C2H5OH+2Na->2C2H5ONa+H2
3)C2H5ONa+HCl->C2H5OH+NaCl
4)C2H5OH(t,H2SO4.)->C2H4+H2O

Answer 2

CO+2H2=CH3OH
CH3OH+HBr=CH3Br
CH3-Br+2Na+Br-CH3=C2H6+2NaBr
C2H6+Cl2=C2H5Cl+HCl
C2H5Cl+NaOH=C2H5OH+NaCl
