Br-CH₂-CH₂-CH₃ + NaOH = OH-CH₂-CH₂-CH₃ + NaBr
OH-CH₂-CH₂-CH₃ + CuO = CH₃-CH₂-CHO + Cu + H₂O
CH₃-CH₂-CHO + 2[Ag(NH₃)₂]OH = CH₃-CH₂-COONH₄ + 3NH₃ + 2Ag + H₂O

2CH₄ = C₂H₂ + 3H₂
3C₂H₂ = C₆H₆
C₆H₆ + Cl₂ = C₆H₅Cl + HCl (cat FeCl₃)
C₆H₅Cl + NaOH = C₆H₅OH + NaCl

CH₃-COONa + NaOH = CH₄ + Na₂CO₃
CH₄ + Cl₂ = CH₃Cl + HCl
CH₃Cl + NaOH = CH₃OH + NaCl
2CH₃OH = CH₃-O-CH₃ + H₂O (H₂SO₄, t<140°)
