1. Conversion of methane to ethane
Step 1 - Treat methane with chlorine gas presence of ultraviolet light
CH4 + Cl2 → CH3-Cl + HCl
Step 2 - Treat chloromethane formed in step 1 with the sodium metal and dry ether (Wrutz synthesis)
2CH3-Cl +2Na → C2H6
2. On treating ethanol with excess of concentrated sulfuric acid, it converts into ethene
CH3-CH2-OH ---(conc. H2SO4)----> CH2=CH2 + H2O
