उत्तर
Ethylene is prepared in the laboratory by dehydration of ethyl alcohol.
Reaction:
\[\ce{CH3Ch2Oh ->[concH2SO4][170°C] CH2 = CH2 + H20}\]
Procedure:
Take one part of ethyl alcohol in a flask. Add two parts of concentrated
sulphuric acid and heat to 170°C.Ethylene is evolved and small amount of aluminium sulphate is also added to the flask to avoid frothing.
Gas is prepared by reacting ethyl alcohol in presence of sulphuric acid and is collected by downward displacement of water.
The gas is dried by passing the gas through sodium hydroxide solution.
