X →443 Kconc. H2SO4 Y ( unsaturated compound)
Z is hydrogen (Colourless gas)
X, Y and Z are alcohol, alkene and hydrogen respectively.
Suppose X is ethanol,it gives alkene on reacting with conc. H2SO4
C2H5OH (X) →443 Kconc. H2SO4 C2H4 (Y)
2C2H5OH →Na2C2H5O-Na+ + H2 (Z)
Role of sulphuric acid: It is used as a dehydrating agent in the above reaction.
