Giải bài 4 trang 23 SGK Hóa học 12 nâng cao

a) Etyl benzoat

$C_6H_5CH_3+3[O] \xrightarrow{{KMnO_4,H^+}} C_6H_5COOH+H_2O$

$C_2H_4+H_2O\xrightarrow{{H^+,{t}^{o}}}CH_3-CH_2OH$

$C_6H_5COOH+CH_3-CH_2OH\overset{{H^+,t^o}}{\leftrightarrows} C_6H_5COOC_2H_5+H_2O$

b) Điều chế 1-etyl-4-metylbenzen: $CH_3-C_6H_4-C_2H_5$

$C_6H_5CH_3+C_2H_4\xrightarrow{{H_2SO_4}} CH_3-C_6H_4-C_2H_5$

c) Điều chế benzyl axetat:  $CH_3COOCH_2C_6H_5$

$C_6H_5CH_3+Cl_2\xrightarrow{{+Cl_2(askt)}}C_6H_5CH_2Cl+HCl$

$C_6H_5CH_2Cl+NaOH \rightarrow C_6H_5CH_2OH+NaCl$

$C_2H_4+H_2O\xrightarrow{{H^+,{t}^{o}}}CH_3-CH_2OH$

$CH_3-CH_2OH+O_2\xrightarrow{{men giấm}} CH_3COOH+H_2O$

$CH_3COOH+C_6H_5CH_2OH\overset{{H^+,t^o}}{\leftrightarrows}CH_3COOCH_2C_6H_5+H_2O$
