KgivesanA compound 'X' on heating with excess conc. sulphuric acid at

1.	KgivesanA compound 'X' on heating with excess conc. sulphuric acid at 443unsaturated compoundgas "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.âY', âX' also reacts with sodium metal to evolve a colourless
Answer» X→443K conc.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→443K conc.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.
