1) 2C2H5Cl+Ca=C4H10+CaCl2
2) CH3COOH+C2H5OH=CH3COOC2H5+H2O
3) C2H6+Br2=C2H5Br+HBr
C2H5Br+NaOH=C2H5OH+NaBr
C2H5OH=H2O+C2H4
C2H4+Br2=C2H5Br
4)CH4+Cl2=CH3Cl+HCl
2 CH3Cl+ Ca=C2H6+CaCl2
C2H6=C2H4+H2
C2H4+H2O=C2H5OH
C2H5OH-------CH3COOH
5)C2H5OH+CH3COOH=>CH3-COO-C2H
6)CH4=>CH3Cl=>C2H6=>C2H4=>CH3-COOH-как4)
7)C2H5OH+HCOOH=>H-COO-C2H5+H2O
8) =4)
9)C2H4=C2H2+H2
10)C6H6+Br2=C6H5Br+HBr
