12个方程式谁会写!
CaC2+2H2O=C2H2(气体)+Ca(OH)2 1
C2H2+2H2=C2H6 2
C2H2+HCl=CH2CHCl 3
nCH2CHCl=[CH2CHCl]n 4
C2H2+H2=CH2CH2 5
CH2CH2+Br2=CH2BrCH2Br 6
nCH2CH2=[CH2CH2]n 7
CH2CH2+H2O=C2H5OH 8
CH3CH2OH浓H2SO4,170度-->CH2=CH2+H2O 9
C2H5OH+O2→(Cu △)CH3CHO+H2O 10
CH3CHO+O2=CH3COOH 11
CH3CH2OH+CH3COOH(浓H2SO4)=CH3COOC2H5+H2O 12
等号写成可逆的,或者箭头
