Question

a compound x on heating with excess concentrated sulphuric acid at 443k gives an unsaturated compound y. x also reacts with sodium metal to evolved a colourless gas z. identity x, y, z. write the equation of the reaction of formation of y. and also write the role of sulphuric acid in the reaction

Answer 1

hey friend

X - Ethanol
Y - Ethene
Z - Hydrogen gas

sulphuric acid acts as dehydrating agent

Answer 2

X - Ethanol
Y - Ethene
Z - Hydrogen gas.

C2H5OH --- at 443 K in presence of hot.concentrated sulphuric acid---->
CH2=CH2 + H2O

Here sulphuric acid acts as a dehydrating agent which removes water from the ethanol to form unsaturated compound Ethene.
