问题描述：

答

乙烯加水＞乙醇，乙醇加氧气＞乙醛，乙醛加新治氢氧化铜＞乙酸，乙酸加乙醇＞乙酸乙酯

答

C2H4+H2O---->CH3CH2OH
2CH3CH2OH+O2---->2CH3CHO+2H2O
2CH3CHO+O2---->2CH3COOH
CH3COOH+CH3CH2OH---->CH3COOCH2CH3+H2O

答

CH2=CH2 + H2O ------ CH3CH2OH
2CH3CH2OH + O2 ------ 2CH3CHO + 2H2O
2CH3CHO + O2 ------ 2CH3COOH
CH3COOH + CH3CH2OH ------ CH3COOCH2CH3 + H2O

答

CH2=CH2+H2O加热加压催化剂→C2H5OH
2C2H5OH+O2(Cu,加热)→2CH3CHO+2H2O
2CH3CHO+O2催化剂加热→2CH3COOH
CH3COOH+C2H5OH(浓H2SO4，加热)→CH3COOC2H5+H2O

答

CH2=CH2 + H2O → CH3CH2OH
2CH3CH2OH + O2 → 2CH3CHO + 2H2O
2CH3CHO + O2→2CH3COOH
CH3COOH + CH3CH2OH → CH3COOCH2CH3 + H2O
