Question

a compound X on heating with excess conc. sulphuric acid at 443K gives an unsaturated compound Y and X also react with sodium metal to evolve a colourless gas Z identify X Y and Z . Write the equation of chemical reaction of formation of Y and also write the role of sulphuric acid in the reaction.

Answer 1

X-ethanol
Y-ethene
Z-Hydrogen gas

equation -

Ethanol + Conc.H2SO4----------->ethene + H2O

Role of sulphuric acid - it acts as a dehydrating agent i.e., it helps in removing water from the compound with which it reacts
