Question

explain the dehydration of alcohol at 413 K temperature​

Answer 1

Answer:

In the presence of sulphuric acid, dehydration of ethanol at 443 K gives ethane, and we get ethoxyethane at 413 K. It is the best method to prepare ether with necessary alcohol.

Answer 2

Answer:

At 110º to 130 ºC an SN2 reaction of the alcohol conjugate acid leads to an ether product. At higher temperatures (over 150 ºC) an E2 elimination takes place. In this reaction alcohol has to be used in excess and the temperature has to be maintained around 413 K.
