Hoàn thành chuỗi phản ứng sao. a) Canxi cacbua -> etin -> etan -> eten -> etanol -> butađien -> cao su buna b) nhôm cacbua -> metan -> axetilen -> vinyl axetilen -> đivinyl -> butan -> etilen -> PE Mong mọi người giúp em với .

a)
$CaC_2+2H_2O\xrightarrow{}Ca(OH)_2+C_2H_2$

 $HC≡CH+H_2\xrightarrow{t^o,Pd/PdCO_3}CH_2=CH_2$
$CH_2=CH_2+H_2O\xrightarrow{H_2SO_4\text{ loãng}}CH_3CH_2OH$
$CH_3CH_2OH\xrightarrow{t^o,xt}CH_2=CH-CH=CH_2+H_2+H_2O$
$nCH_2=CH-CH=CH_2\xrightarrow{t^o,P,xt}(-CH_2-CH=CH-CH_2-)_n$
b)
$Al_4C_3+12H_2O\xrightarrow{}4Al(OH)_3+3CH_4$
$2CH_4\xrightarrow{1500^oC, \text{làm lạnh nhanh}}C_2H_2+3H_2$

$2HC≡CH\xrightarrow{t^o,xt}CH≡C-CH=CH_2$

$CH≡C-CH=CH_2+H_2\xrightarrow{t^o,Pd/PdCO_3}CH_2=CH-CH=CH_2$

$CH_2=CH-CH=CH_2+H_2\xrightarrow{t^o, Ni}CH_3CH_2CH_2CH_3$
$C_4H_10\xrightarrow{t^o,xt}C_2H_4+C_2H_6$

$nCH_2=CH_2\xrightarrow{t^o,xt,P}(-CH_2-CH_2-)_n$
