Question

what is the action of concentrated h2so4 on ethanol at 453k?​

Answer 1

Answer:

When ethanol is heated with conc.sulphuric acid at 453k, dehydration takes place and ethene is formed.

In this reaction sulphuric acid acts as a dehydrating agent.

Answer 2

The action of concentrated sulphuric acid  on ethanol at 453k​

Explanation:

Ethanol

• It is a member of alcohol .
• Its molecular formula is C₂H₅OH

Sulphuric acid

1. The sulphuric acid is king of chemicals .
2. It act as dehydrating agent that is it can extract the water from compound ,
3. When it is treated with ethanol , it extracts water (dehydrating property ) and at 453 K it forms ethene .
4. This is also called as dehydration of alcohol .
5. The reaction involved is :

CH₃CH₂OH ------------------> CH₂CH₂  + H₂O

           (action of H₂SO₄)
