C2H6 + Cl2 -hv-> C2H5Cl + HCl
C2H5Cl + NaOH(p-p) -> NaCl + C2H5OH
C2H5OH + [O] -> CH3CHO
CH3CHO -LiAlH4-> CH3CH2OH
CH3CH2OH -H2SO4,t-> H2C=CH2
H2C=CH2 + H2O -H2SO4,t-> CH3CH2OH
C2H5OH + [O] -> CH3CHO
CH3CHO + [O] -> CH3COOH
CH3COOH + CH3OH -H(+)-> H2O + CH3C(=O)OCH3
2CH3COOCH3 + Cu(OH)2 -kat,t> (CH3COO)2Cu + 2CH3OH
