Question

Name the product formed when ethanol is heated at 443 K with concentrated sulphuric acid. State the role of sulphuric acid in the reaction(other than acting as a catalyst). Write the chemical equation of this reaction.

Answer 1

the product formed is ethene
and sulphuric acid acts a dehydrating agent
reaction:-
C2H5OH-------->C2H4+H2O
Surely in presence of sulphuric acid and at temperature of 443K

Answer 2

The ethene is the product formed as a product from ethanol.  

Explanation:

• This reaction is called a dehydration reaction. Hence on heating the 'ethanol at 443 K' with concentrated 'sulphuric acid' leads to the formation of ethane.
• This is the manner, the reaction occurs resulting in the formation of ethene. Ethene is used as automobile antifreeze agent and precursor to polymers’

The chemical equation of this reaction is as follows.

$C_{2}H_{5}OH$ = $C_{2}H_{4} + H_{2}O$.
