A]Carbondioxide and water is formed along with some heat and light.
C2H5OH + 3O2 ----------- 2CO2 + 3H20 +HEAT
It is an exothermic redox reaction.
B] It produces ethene.
C2H5OH CONC.H2SO4 CH2 = CH2 + H2O
------------------------
443K
It is dehydration reaction.
C] Sodium ethoxide is formed.
CH3CH2OH + NA ---------- CH3CH2ONA + H2
