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:  \(CH_3COOCH_2C_6H_5\)

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

\(C_6H_5CH_2Cl+NaOH \rightarrow C_6H_5CH_2OH+NaCl\)

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

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

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