प्रश्न
State how the following conversions can be carried out:
Ethyl alcohol to Ethane
उत्तर
When concentrated sulphuric acid is added to ethyl alcohol, it causes dehydration to give ethene. Ethene reacts with hydrozen in presence of Ni to give ethane.
\[\ce{C2H5OH ->[Conc.H2SO4][170°] CH2 = CH2 + H2O}\]
\[\ce{CH2 = CH2 + H2 ->[Ni][300°C] CH3 - CH3}\]
