Giải thích các bước giải:

`a.` `C_2H_4 + H_2O` $\xrightarrow[]{t^o,H_2SO_4}$ `C_2H_5OH`

`H_2S + Li(C_2H_5OH)` $\xrightarrow[]{ête}$ `C_2H_5OH + LiHS`

`CH_3CHO + H_2 -> C_2H_5OH`

`NaOH + HCOOC_2H_5 -> C_2H_5OH + HCOONa`

`b.` `CH3COONa + HCl` $\xrightarrow[]{xt}$ `CH3COOH + NaCl `

`CH3COONa + HNO3 -> CH3COOH + NaNO3`

`2CH3COONa + H2SO4 -> 2CH3COOH + Na2SO4`

`CH3COOC2H5 + H2O ` $\xrightarrow[]{xt:H^+}$ `C2H5OH + CH3COOH`

Viết 4 PTHH điều chế ethanol

H2C=CH2+ H2O -->CH3CH2OH

C6H12O6 -->2 CH3CH2OH+ 2CO2

C2H5OCl+NaOH-->C2H5OH+NaCl

CH3COOC2H5 + H2O  --> C2H5OH + CH3COOH

Viết 4 PTHH điều chế acetic acid

2CH10 + 3O2 (xúc tác, t^o) --> 4CH3COOH + 2H2O

CH3CH2OH + O2  --> CH3COOH + 2H2O

C2H5OH + O2 --> CH3COOH + H2O

CH3OH + CO (xúc tác CO, to)  --> CH3COOH
