प्रश्न
A compound 'X' on heating with excess conc. sulphuric acid at 443 K gives an unsaturated compound 'Y'. 'X' also reacts with sodium metal to evolve a colourless gas 'Z'. Identify 'X', 'Y' and 'Z'. Write the equation of the chemical reaction of formation of 'Y' and also write the role of sulphuric acid in the reaction.
उत्तर
X, Y and Z are alcohol, alkene and hydrogen respectively.
Suppose X is ethanol, it gives alkene on reacting with conc. H2SO4
Role of sulphuric acid: It is used as a dehydrating agent in the above reaction.
