Question

Осуществить превращения. cuco3-> cac2-> c2h2-> ch3-ch2-oh-> ch3-ch2-cl-> ch2=ch2

Answer 1

1) CaCO3+3C=(t 2000, сплав)CaC2+CO+CO2

2)CaC2+2H2O=Ca(OH)2+C2H2

3)C2H2+H2=(t,Ni)C2H4

4)C2H4+H2O=C2H5OH

5)C2H5OH+Hcl(к)=C2H5Cl+H2O

6)C2H5CL+NaOH(спирт)=C2H4+NaCl+H2O

Answer 2

CaCO₃ -> CaC₂ -> C₂H₂ -> CH₃-CH₂-OH -> CH₃-CH₂-Cl -> CH₂=CH₂

1)

2) CaC₂ +2 H₂O = Ca(OH)₂ + HC≡CH

3) HC≡CH + H₂ ->(при t, катал.)-> H₂C=CH₂

H₂C=CH₂ + H₂O -> H₃C-CH₂OH

4)C₂H₅OH + HCl -> C₂H₅Cl + H₂O

5)
