Answer 1

Ответ:

Объяснение:

а) C2H5OH-> CH2=CH2 + H2O (H2SO4, t)

   CH2=CH2 + H2 -> CH3-CH3 (t, kat)

   CH3-CH3 + Cl2 -> CH3-CH2-Cl + HCl  (hy)

   C2H5Cl + NaOH -> C2H5OH + NaCl

  C2H5OH + CuO -> CH3COH + Cu + H2O

б) CaCO3 + 3C -> CaC2 + CO + CO2

   CaC2 + 2H2O = Ca(OH)2 + CH=-CH

CH=-CH + H2 -> CH2=CH2

CH2=CH2 + HOH -> CH3-CH2-OH

CH3-CH2-OH + HCl  =  CH3-CH2-Cl + H2O

CH3-CH2-Cl + KOH -> CH2=CH2 + KCl + H2O
