Write the name and structural formula of the compound formed when ethanol is heated at 443K temperature with excess of conc. `H_(2)SO_(4)`. What is the role of conc. `H_(2)SO_(4)` in this reaction ? Also give the chemical equation for the reaction.

Explanation

The name of the compound formed is Ethene and its structural formula is

`underset"Ethanol"(CH_(3)CH_(2))OHoverset(conc.H_(2)SO_(4))underset "443K"rightarrow underset"Ethene"(CH_(2))=CH_(2)+H_(2)O`
Role of `H_(2)SO_(4)`: It work asla catalyst to initiate the reaction to lose watermolecule to form alkene.
