Answer 1

C2H5OH+H2SO4（加热）→CH2=CH2↑+H2O
C+(浓)2H2SO4=CO2↑+2SO2↑+2H2O
CH≡CH+2Br2→CHBr2CHBr2
CaC2+2H2O→C2H2↑+Ca(OH)2
Al4C3+12H2O→4Al(OH)3+3CH4
C6H5-CH3+Cl2（光）→C6H5-CH2Cl
C6H6-CH3+H2(Ni催化)→C12H11-CH3
C2H5-Br+H2O→C2H5OH+HBr
BrCH2CH2Br+2NaOH（醇加热）→CH≡CH+2NaBr+2H2O
BrCH2CH2Br+2NaOH（水加热）→HOCH2CH2OH+2NaBr
CH3CH2OH+HBr（加热）→CH3CH2Br
2CH3CH2CH2OH+O2（催化剂加热）→2CH3CH2CHO+H2O
CH3CH（-CH3）CH2OH+HBr→CH3CH（-CH3）CH2Br+H2O
