Question

Do following conversations.

1. Bromo methane to Ethan

2. Ethanoic acid to bromo methane

3.Methane to Ethane

4.Ethane to Methanal

5.Ethyne to Benzene

Answer 1

!) H₃C-Br + 2Na _Dry ether> H₃C-CH₃
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
