1.	A compound 'X'on heating with excess conc. sulphuric acid at 443 K gives an unsaturated compound Y X'also reacts with sodiummetal to evolve a colourless gas Z'. Identify X', Y'and 'Z'. Write the equation of the chemical reaction of formation of 'Y' and alsowrite the role of sulphuriÄ acid in the reaction.on heating with excess conc, sulphĂşric acid atAND MEDICAL PREPARATION
Answer» X→443Kconc.H2SO4Y ( 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)→443Kconc.H2SO4 C2H4(Y) 2C2H5OH→Na2C2H5O-Na++ H2(Z) Role of sulphuric acid: It is used as a dehydrating agent in the above reaction.

Answer»

X→443Kconc.H2SO4Y ( 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)→443Kconc.H2SO4 C2H4(Y)

2C2H5OH→Na2C2H5O-Na++ H2(Z)

Role of sulphuric acid: It is used as a dehydrating agent in the above reaction.
