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

This reaction involves organic compounds.
To be specific, the organic compound X is an Alkanols.
We will thus look at two chemical properties of alkanols.
When alkanols are heated with excess concentrated sulphuric acid an alkene is formed.
The sulphuric acid in this reaction acts as a dehydrating agent that is it removes the water molecules in the compound to form an unsaturated compound.
When alkanols are reacted with group one metals such as Sodium metal, the hydrogen in the alkanols is displaced to give hydrogen gas.
From the information above we can take an example of an Alkanol such as Ethanol to be X.
When Ethanol is dehydrated it forms a respective alkene which is ethene.
The gas produced when ethanol is reacted with Sodium metal is hydrogen gas.
The equation for the production of ethene is :
CH₃ - CH₂OH ---- conc. H₂SO₄ (hot)----> CH₂ = CH₂ + H₂O
X = Ethanol
Y = Ethene
Z = hydrogen gas
