Ethyl alcohol is heated with concentrated `H_(2)SO_(4) at 170^(@)C`. The product formed is

A

ethyl hydrogen sulphate

B

diethyl sulphate

C

ethylene

D

diethyl ether

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(OH)underset(|)CH_(2)-underset(OH)underset(|)CH_(2)underset(170^(@)C)overset(Conc.H_(2)SO_(4))rarrCH_(2)=CH_(2)+H_(2)O`
Ethyl hydrogen sulphate, `C_(2)H_(5)OSO_(2).OH`, is formed in the cold, but on heating to about `170^(@)C`, it decomposes into ethylene and sulphuric acid.
