In cold countries Ethanol is used as an antifreeze.
In order to do the hydrogenation of the unsaturated hydrocarbons we use the catalyst Nickel.
Addition of oxygen and removal hydrogen from any substance is known as oxidation.
Think about what happens when a substance undergoes combustion.
Concentrated sulphuric acid is used as a dehydrating agent in the process of getting ethene from ethanol.
As the carbon carbon bonds and carbon hydrogen bonds are very strong in the organic compounds so saturated hydrocarbons are quite unreactive to most of the reagents but they do undergo substitution reaction in the presence of heat and light .
Concentrated sulphuric acid is used as a dehydrating agent in the process of getting ethene from ethanol.
As the govenment imposes only a small amount of excise duty to the alcohol supplied to industries in order to supply cheap alcohol to them. So to stop its misuse for drinking purposes the alcohol is denatured by adding methanol ,pyridine,copper sulphate etc.
When sodium reacts with ethanol in the cold it gives sodium ethoxide.
