Question

A compound x on heating with excess concentrated sulphuric acid at 443 k gives an unsaturated compound why it's also reacts with sodium metal to evolve a colourless gas z identify xyz write the chemical equation of the chemical reaction of formation of wife and also write the role of the sulphuric acid in the reaction

Answer 1

sulphuric acid acts as a dehydrating agent in the reaction and compound X is ethanol CH3CH2OH ,the colourless gas z is hydrogen H2

Answer 2

X - Ethanol: C2H5OH / Ethyl Alcohol

Y - Ethene: (C2H4)

Z - Hydrogen: (H2)

Ethanol react in the presence of sulphuric acid to give ethene and water

Role of sulphuric acid: dehydrating agent
