Ethyl alcohol is industrially prepared from ethylene by
- Permanganate oxidation
- Catalytic reduction
- Absorbing in $H_2SO_4$ followed by hydrolysis
- Fermentation.
The Correct Option is C
Approach Solution - 1
Approach Solution -2
Ans: Ethyl alcohol is prepared by absorbing H₂SO₄followed by hydrolysis. The equation for the same is as follows:
C₂H₄ + H₂O → C₂H₅OH
The catalyst that is used in this process is a strong acid like sulphuric acid. At industrial level the temperature and the conditions need to be maintained. The pressure and concentration of the catalyst is taken into consideration so that optimised yield and efficiency of the process is maintained. This is used for a large production and has applications like fuel, in pharmaceuticals and beverages etc.

Concepts Used:
Alcohols, Phenols, and Ethers
Alcohol is formed when a saturated carbon atom bonds to a hydroxyl (-OH) group. It is an organic compound that contains a hydroxyl functional group attached to a carbon atom.
Phenol is formed when the -OH group replaces the hydrogen atom in benzene. It is an organic compound in which a hydroxyl group directly attaches to an aromatic hydrocarbon.
Ether is formed when oxygen atom bonds to two alkyl or aryl groups. It is an organic compound that has an oxygen atom that is connected to two aryl and alkyl groups.
