Hoàn thành dãy chuyển hóa sau(ghi rõ điều kiện pứ)

a. C2H6O->CO2->Na2CO3->NaHCO3->NaCl

b.Etilen->rượu etylic->axit axetic->etyaxetat->axit axetic->bari axetat->natri axetat->metan

Answer 1

\(a,C_2H_6O+3O_2\xrightarrow[]{t^o}2CO_2+3H_2O\\ CO_2+2NaOH\rightarrow Na_2CO_3+H_2O\\ Na_2CO_3+CO_2+H_2O\rightarrow2NaHCO_3\\ NaHCO_3+HCl\rightarrow NaCl+CO_2\uparrow+H_2O\)

\(b,C_2H_4+H_2O\xrightarrow[axit]{t^o}C_2H_5OH\\ C_2H_5OH+O_2\underrightarrow{\text{men giấm}}CH_3COOH+H_2O\\ CH_3COOH+C_2H_5OH\xrightarrow[t^o]{H_2SO_{4\left(đặc\right)}}CH_3COOC_2H_5+H_2O\\ 2CH_3COOH+BaO\rightarrow\left(CH_3COO\right)_2Ba+H_2O\\ \left(CH_3COO\right)_2Ba+Na_2SO_4\rightarrow2CH_3COONa+BaSO_4\downarrow\\ CH_3COONa+NaOH\rightarrow Na_2CO_3+CH_4\uparrow\)
