А) 2CH4=C2H2+3H2
C2H2+2HCl=C2H4Cl2
C2H4Cl2+Zn=ZnCl2+C2H4
б)
CH=-C-CH2-CH(CH3)-CH3+2HBr изб=CH3-CBr2-CH2-CH(CH3)-CH3
CH3-CBr2-CH2-CH(CH3)-CH3+NaOHспирт=CH3-C=-C-CH(CH3)-CH3+2NaBr+2H2O
в)
C2H4+Cl2=C2H4Cl2
C2H4Cl2+2NaOH=C2H2+2NaCl+2H2O
3C2H2=C6H6
2)Неполное каталитическое
окисление:
C2H6 + O2 = CH3CHO + H2O
