Ethyl alcohol (in excess) is heated with concentrated `H_(2)SO_(4)` at `40^(@)C`. On distillation, the major product that separates out is

A

diethyl sulphate

B

ethyl hydrogen sulphate

C

ethene

D

ethoxyethane

Text Solution

Verified by Experts

The correct Answer is:
D
When a mixture of ethyl alcohol (in excess) and conc. `H_(2)SO_(4)` is heated to a tempreture to a temperature below that required to form ethene, intermolecular dehydration occurs instead of intramolecular dehydration.
`CH_(3)CH_(2)-OH+H-OCH_(2)CH_(3)overset(Conc. H_(2)SO_(4))(rarr)CH_(3)CH_(2)-O-CH_(2)CH_(3)+H_(2)O`
The ether always has a lower boiling point than the parent alcohol and is distilled off as it forms.
