Solution
Ethene is first treated with concentrated sulphuric acid at 80°C to form ethyl hydrogen sulphate. Ethyl hydrogen sulphate, on hydrolysis with boiling water or steam, yields ethanol.
\[\ce{CH2 = CH2 + H2SO4 ->[80^\circ C][30 atm] CH3CH2HSO4}\]
\[\ce{CH3CH2HSO4 + HOH ->[boiling] CH3CH2OH + H2SO4}\]
