A compound 'X' on heating with excess concentrated sulphuric acid at 4

1.	A compound 'X' on heating with excess concentrated sulphuric acid at 443K gives an unsaturated compound 'Y' 'X' also react swithodium metal to evolve a colourless gas Z'.Identify X',Y'and Z'. Write the equation of the chemical reaction of formationof r
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.
