Ethene to Ethyl alcohol.
Advertisements
Solution 1
Ethene adds a molecule of water in the presence of mineral acids to form ethyl alcohol.
\[\ce{CH2 = CH2 + H2O ->[H+] CH3 - CH2 - OH}\]
Solution 2
\[\ce{\underset{ethene}{CH2 = CH2} + H2SO4 -> \underset{hydrogen sulphate}{\underset{ethyl}{C2H5HSO4}} -> \underset{ethanol}{C2H5OH} + \underset{Sulphuric acid}{H2SO4}}\]
