a,CaCO3->A->B->C2H2->C->D->E->C2H5OH
b,C2H5OH->A->B->C2H5OH
c, C2H5OH->C->D->C2H5OH

a)
CaCO3 -to-> CaO + CO2
CaO + 3C -to-> CaC2 + CO
CaC2 + H2O ---> Ca(OH)2 + C2H2
C2H2 + H2 -Pd,to-> C2H4
C2H4 + H2 -Ni,to-> C2H6
C2H6 + Cl2 -a's'-> C2H5Cl + HCl
C2H5Cl + NaOH ---> NaCl + C2H5OH

b)
C2H5OH + O2 -men giấm-> CH3COOH + H2O
CH3COOH + C2H5OH -H+,to-> CH3COOC2H5 + H2O
CH3COOC2H5 + NaOH ---> CH3COONa + C2H5OH

c)
C2H5OH -đề hidrat-> C2H4 + H2O
C2H4 + HCl ---> C2H5Cl
C2H5Cl + NaOH ---> NaCl + C2H5OH
