Answer 1

1) 2CH4-->C2H2+3H2 (1500°C)
2) C2H2+2H2-->C2H6 (кат. Ni, t)
3) В одну стадию тут ну никак не выйдет. Можно в три:
C2H2+2,5O2-->2CO2+Н2О
СО2+3Н2-->СН3ОН+Н2О
СН3ОН+HCl-->CH3Cl+H2O
4) СаС2+2Н2О-->Са(ОН)2+С2Н2↑
5) C2H5Cl+KOH(H2O)-->C2H5OH+KCl
6) C2H5Cl+KOH(сп.)-->С2Н4+KCl+H2O
7) C2H5OH+CuO-->CH3CHO+Cu+H2O
8) CH3CHO+H2-->C2H5OH (кат. Ni, t)
9) C2H4+H2O-->C2H5OH (кат. H2SO4)
10) nCH2=CH2-->-(CH2-CH2)-n (t, p)
11) 2C2H5OH-->C2H5-O-C2H5+H2O (кат. H2SO4)
12) CH3CHO+Ag2O(NH3)-->CH3COOH+2Ag↓
13) CH3Cl+KOH(H2O)-->CH3OH+KCl
14) 2CH3OH-->CH3-O-CH3+H2O
15) CH3OH+CuO-->HCHO+Cu+H2O
16) HCHO+H2-->CH3OH (кат. Ni, t)
17) HCHO+Ag2O(NH3)-->HCOOH+2Ag↓
18) HCOOH+NaHCO3-->HCOONa+H2O+CO2↑
19) C2H6+Cl2-->C2H5Cl (hv)
