1) CH3-CH3 +Cl2 -> (свет) CH3-CH2-Cl + HCl
2) CH3-CH2-OH + HCl -> CH3-CH2- Cl +H2O
3) СH3-CH2-Cl + KOH (водный р-р.) -> CH3-CH2-OH +KCl
4) CH3-C=O + H2 -> (Ni) CH3-CH2-OH

H
5) CH3-CH2-OH -> ( [O] KMnO4) CH3-C=O

H
6) CH3-CH2-OH -> (H2SO4(к.) t<140град) CH2=CH2
7)CH2=CH2 + HOH -> (H2SO4 (к)) CH3-CH2-OH
8) CH2=CH2 + H2 -> (Ni t) CH3-CH3
9) CH3-CH3 -> (Ni t) CH2=CH2
10) CH2=CH2 ->(Ni t) H2 + CHтройная связьСH
11)CHтройная связьСH + H2 ->(Ni t) CH2=CH2
12)CHтройная связьСH + H2 ->(Ni t) CH2=CH2
CH2=CH2+ H2 -> (Ni t) CH3-CH3
13)CH3-CH3 -> (Ni t) 2H2 + CHтройная связьСH
14) CH3-C=O + [Ag(NH3)2]OH -> (t) CH3-COOH + Ag↓ + NH3+ H2O

Cl
16)
17) CH2=CH2 + H2 -> (Ni t) CH3-CH3
CH3-CH3 +Cl2 -> (свет) CH3-CH2-Cl + HCl
18) CH3-CH2-Cl + KOH (спирт. р-р) -> CH2=CH2
в решении не уверена, надеюсь
2K+ 2H2O=2KOH+H2
2K+S=K2S
2K+H2=2KH
