Question

A compound x on heating with excess concentric sulphuric acid at 4:43 K give gives and unsaturated compound why acid react with sodium metal to evolve a colourless gas Z identify x y z write the equation of the chemical reaction formation of Y and also write the role of sulphuric acid in the reaction

Answer 1

X is ethanol.
Y is ethene.
Z is hydrogen gas.
The reaction involved to get ethene is :-
CH3CH2OH → C2H4
The role of conc. Sulphuric acid is that it dehydrates ethanol to give ethene and is thus referred to as a dehydrating agent.
