1.	A compound 'X' on heating with excess cone. sulphuric acid at 443 K gives anĂźnsaturated compound 'Y'. X' also reacts with sodium metal to evolve a colourlessgas Z'. Identify X', 'Y' and Z'. Write the equation of the chemical reaction offormation of 'Y' and also write the role of sulphuric acid in the 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.

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.
