CaC2- больше C2h2- больше CH3OH- больше C2H5OH- больше C2H4- больше C2H5- больше C2H5OH- больше C4H6- больше C4H8Br2

1)CaC2+2HOH=Ca(OH)2+C2H2 2)2C2H2+5O2=4CO2+2H2O CO2+C=2CO CO+2H2=CH3OH 3)CH3OH+HCl=CH3Cl+H2O 2CH3Cl+2Na=2NaCl+C2H6 CH3-CH3+Cl2=CH3-CH2Cl+HCl CH3-CH2Cl+KOH=CH3-CH2OH +KCl 3)C25OH=C2H4+H2O   4)C2H4+H2=C2H6 5)C2H6+Cl2=C2H5Cl+HCl C2H5Cl+NaOH=C2H5OH+NaCl C2H5OH+HCl=C2H5Cl+H2O 2C2H5Cl+2Na=2NaCl+C4H10 C4H10=C4H6+2H2 C4H6+2HBr=C4H8Br2
