ch3ch2cooh+ch3ch2oh=神马+h20 求救啊
CH3CH2OH CH3CH2COOH Na2CO3 NaHCO3 苯酚 苯环上连-COOH
H2O、CH3CH2OH 为什么h20 酸性强于 ch3ch2oh
ch3ch2oh+h2o=什么?
CH3CHO+CH3CH2OH=?
+hcl=bacl2 +h20
To be ideal,to be not before anymore.神马意思啊,求救
SO2+H20=?生成什么?
HCl+HClO=Cl2+H20
CH3CH2Br+NaOH=H2O △CH3CH2OH+NaBr
13,有四种有机物①CH2=CHCH2OH ②CH3CH2COOH ③CH2=CHCOOH ④HOCH2CHO.
performance-based grants 是神马意思哟.看书看不懂 求救.
解释一个方程式:CH3-CH2-CH=CH2加入酸性高锰酸钾溶液中,产生CO2 和 CH3CH2COOH,为的么?
