Giúp e bài 5 đi ạ

Answer 1

a)

(1)  \(CH_4+Cl_2\underrightarrow{as}CH_3Cl+HCl\)

(2) \(CH_3Cl+NaOH\underrightarrow{t^o}CH_3OH+NaCl\)

(3) \(CH_3OH+CuO\underrightarrow{t^o}HCHO+H_2O+Cu\)

(4) \(2HCHO+O_2\underrightarrow{t^o,xt}2HCOOH\)

b)

(1) \(CH_3CH_2OH+CuO\underrightarrow{t^o}CH_3CHO+H_2O+Cu\)

(2) \(2CH_3CHO+O_2\underrightarrow{t^o,xt}2CH_3COOH\)

(3) \(CH_3COOH+Na\rightarrow CH_3COONa+\dfrac{1}{2}H_2\)

(4) \(CH_3COONa+NaOH\underrightarrow{t^o,CaO}CH_4+Na_2CO_3\)

c)

(1) \(CH_3CH_2OH\underrightarrow{170^oC,H_2SO_4}CH_2=CH_2+H_2O\)

(2) \(2CH_2=CH_2+O_2\underrightarrow{t^o,xt}2CH_3-CHO\)

(3) \(2CH_3-CHO+O_2\underrightarrow{t^o,xt}2CH_3COOH\)

(4) \(CH_3COOH+C_2H_5OH\underrightarrow{t^o,H_2SO_4}CH_3COOC_2H_5+H_2O\)
