Đáp án:
Giải thích các bước giải:
Câu 24 :
$C_2H_2 + H_2O \xrightarrow{xt} CH_3CHO$
$CH_3CHO + H_2 \xrightarrow{t^o,xt} CH_3CH_2OH$
$CH_3CH_2OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O$
$CH_3COOH + C_2H_5OH \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O$
Câu 25 :
$CH_3COOCH=CH_2 + NaOH \to CH_3COONa + CH_3CHO$
$CH_3CHO + 2AgNO_3 + 3NH_3 + H_2O \xrightarrow{t^o} 2Ag + 2NH_4NO_3 + CH_3COONH_4 $
$CH_3COONH_4 + NaOH \xrightarrow{t^o} NH_4 + CH_3COONa + H_2O$
$A : CH_3COONa$
$B : CH_3CHO$
$F : CH_3COONa$
