Câu 2.
$a,$
$(1) CH_{3}COOH + NaOH \xrightarrow{\text{$t^{o},CaO$ }} CH_{4} + Na_{2}CO_{3} $
$(2) 2CH_{4} \xrightarrow{\text{$1500^{o}C,làm lạnh nhanh$ }} C_{2}H_{2} + 3H_{2}$
$(3) C_{2}H_{2} + H_{2} \xrightarrow{\text{$t^{o},Pd , PbCO_{3}$ }} C_{2}H_{4} $
$(4) C_{2}H_{4} + H_{2} \xrightarrow{\text{$t^{o},Ni$ }} C_{2}H_{6} $
$(5) C_{2}H_{6} + Cl_{2} \xrightarrow{\text{$askt$ }}C_{2}H_{5}Cl + HCl$
$b, $
$(1) C_{2}H_{6} + Cl_{2} \xrightarrow{\text{$askt$ }}C_{2}H_{5}Cl + HCl$
$(2) C_{2}H_{6} → C_{2}H_{4} + H_{2} $
$(3) C_{2}H_{4} + H_{2} \xrightarrow{\text{$t^{o},Ni$ }} C_{2}H_{6} $
$(4) C_{2}H_{4} + HCl → C_{2}H_{5}Cl $
$(5) nCH_{2} = CH_{2} \xrightarrow{\text{$t^{o},xt ,p$ }} (- CH_{2} - CH_{2} - )_{n}$
$(6) C_{2}H_{4} + H_{2}O \xrightarrow{\text{$H_{2}SO_{4}(l)$ }} C_{2}H_{5}OH $
$(7) C_{2}H_{5}OH \xrightarrow{\text{$170^{o}C,H_{2}SO_{4}$ }} C_{2}H_{4} + H_{2}O$
$(8) C_{2}H_{2} + 2H_{2} \xrightarrow{\text{$t^{o},Ni$ }} C_{2}H_{6} $
$(9) C_{2}H_{2} + H_{2} \xrightarrow{\text{$t^{o},Pd , PbCO_{3}$ }} C_{2}H_{4} $
$(10) 2C_{2}H_{2} \xrightarrow{\text{$t^{o} , xt$ }} C_{4}H_{4} $
$(11) C_{2}H_{2} + 2AgNO_{3} + 2NH_{3} → C_{2}Ag_{2} + NH_{4}NO_{3} $
$(12) C_{2}Ag_{2} + 2HCl → C_{2}H_{2} + 2AgCl$
