Ethene is formed when ethanol at $443\, K$ is heated with excess of concentrated sulphuric acid. What is the role of sulphuric acid in this reaction? Write the balanced chemical equation of this reaction.
(N/A) In this reaction,concentrated sulphuric acid acts as a dehydrating agent,which removes a water molecule from the ethanol molecule.
The balanced chemical equation is:
$CH_3CH_2OH \xrightarrow[443\, K]{\text{Hot conc. } H_2SO_4} CH_2=CH_2 + H_2O$
The balanced chemical equation is:
$CH_3CH_2OH \xrightarrow[443\, K]{\text{Hot conc. } H_2SO_4} CH_2=CH_2 + H_2O$
