Решить цепочьку: al4c3 = ch4 = ch3cl = c2h6 = c2h5cl = c4h10 = c4h9br

Al4C3+12H2O=3CH4+4Al(OH)3
CH4+Cl2=CH3Cl+HCl
CH3Cl+CH3Cl+2Na=2NaCl+C2H6
C2H6+Cl2=C2H5Cl+HCl
C2H5Cl+C2H5Cl+2Na=2NaCl+C4H10
C4H10+Br2=C4H9Br+HBr

Al4C3 +12H2O  t 1500> 3CH4 + 4Al(OH)3
CH4 + Cl2 > CH3Cl + HCl
2CH3Cl + 2Na >  2NaCl+ C2H6
C2H6 + Cl2 > HCl + C2H5Cl
2C2H5Cl + 2Na > 2NaCl + C4H10
C4H10 + Br2 > C4H9Br + HBr
