CH3CH2OH+Cu/O2→(△)CH3CHO

2CH3CH2OH+O2—Cu,△→2CH3CHO+2H2O 这是反应总方程式,那 2CH3CH2OH+O2→2CH3CHO+2H2O和CH4+2O2→CO2+2H2O那个是取代反应 2 CH3CH2OH + O2 == 2 CH3CHO + 2 H2O 下列有关反应2CH3CH2OH(l)+O2(g)=Cu=2CH3CHO(l)+2H2O(l)的说法错误的是 2CH3CH2OH＋O2 催化剂————→Δ 2CH3CHO＋2H2O是什么反应、? CH3CHO+CH3CH2OH=? 2CH3CH2OH+02=2CH3CHO+2H2O 2CH3CH0+O2==2CH3COOH CH3CH2OH+CH3C CH3CH2OH+cu(OH)2+NAOH→? CH3CH2OH→①CH3CHO→②CH3COOH→③CO2+H2O 用一种试剂鉴别 CH3COOH CH3CHO CH3CH2OH CH3COOCH2CH3 CH3CH2OH如何反应生成CH3CHO的方程式是啥 为什么下面最佳答案中CH3CHO要改成CH3CH2OH?
