Question

Помогите составить уравнения реакций:
CH3-CH2-OH->CH2=CH2=CH-CH=CH2
CaCO3->CaC2->C2H2->CH3-CH2-OH->CH3-CH2-Cl->CH2=CH2

Answer 1

H3C-CH2-OH+H3C-CH2-OH (Al2O3, ZnO)=H2C=CH-CH=CH2+H2+2H2O ; CaCO3=CaO+CO2 , CaO+3C (t=2000)=CaC2+CO , CaC2+2H2O=C2H2+Ca (OH) 2 , C2H2+H2 (t, p, Ni)=C2H4 , C2H4+H2O (H3PO4)=C2H5OH , C2H5OH+HCl=C2H5Cl+H2O , C2H5Cl+KOH (спирт)=С2Н4+KCl+H2O
