Question

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

Answer 1

Answer:

X = Ethanol ( CH3CH2OH)

Y= Ethene (C2H4)

Z= Hydrogen Gas (H2)

Explanation:

When ETHANOL is heated with concentrated sulphuric acid at 443 K, dehydration takes place and ETHENE is formed. In this reaction concentrated sulphuric acid acts as a dehydrating agent or catalyst.

CH3CH2OH —> C2H4

Ethanol also reacts with Sodium to give Hydrogen gas.

CH3CH2OH + Na —> CH3CH2ONa + H2
