!) H₃C-Br + 2Na _Dry ether> H₃C-CH
2) Add NaOH+CaO > methane is form'd > Add Br₂ water > bromomethane is formed
3 ) Methane+ Cl₂ in presence of sunlight >> chloromethane is form'd >>Wurtz Reaction >> Ethane is form'd
4) ethane +KMnO₄ >> ethanoic acid >> NaOH+CaO >> methane + H₂O >> methanol >> PCC or Cu at 573 K >> methanal
5) cyclic polymerization
