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

A

`CH_(3)=overset(overset(O)(||))(C)-OC_(2)H_(6)`

B

`C_(2)H_(6)`

C

`C_(2)H_(4)`

D

`C_(2)H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
3
Ethyl alcohol on dehydration with conc. `H_(2)SO_(4)` at `170^(@)C` give ethylene.
`CH_(3)-CH_(2)-OH underset("conc."H_(2)SO_(4)
("ethylene"))overset(170^(@)C)rarr CH_(2)=CH_(2)+H_(2)O`
