Question

Ethyl alcohol is industrially prepared from ethylene by

• A. Permanganate oxidation
• B. Catalytic reduction
• C. Absorbing in $H_2SO_4$ followed by hydrolysis
• D. Fermentation.

Answer 1

The Correct Option is C

$ {C_2H_5 - NH_2 ->[HNO_2] C_2H_5OH +N_2 +H_2O}$

Answer 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.
