The the compound C₂H₅OH is ethanol.
The first reaction, is heating of ethanol in the presence of Al₂O₃ as a catalyst:
Al₂O₃
C₂H₅OH--------------> C₂H₄ + H₂O
350°
This reaction is called dehydration reaction. It involves the dehydration of ethanol or ethyl alcohol to form ethene. The compound A thus is ethene.
This reaction can also take place when ethanol is heated under 250° but by using a combination phosphoric acid and aluminium oxide as a catalyst.
Ethanol can also be converted to ethene when heated at 170° while using concentrated sulphuric acid (conc. H₂SO₄)as a catalyst
------------------------------------------------------------------------------------------------------
The next step involves the reaction of ethene(compound A) with bromine to form bromoethane(1,2-dibromoethane to be specific)--This is the compound B. The reaction is as follows:
CH2=CH2 + Br2 --------------> CH2Br-CH2Br
------------------------------------------------------------------------------------------------------
The lower equation is the catalytic conversion of ethene to ethane by heat of 250°. The equation make use of finely divided nickel metal and hydrogen as catalyst. The hydrogen gets added to the ethene to form ethane. The reaction is as follows:
CH2=CH2 + H2 ------------------> CH3-CH3
The compound C is ethane.
