Discuss the reaction and mechanism of acidic dehydration of ethyl alcohol to prepare ether.

Text Solution

Verified by Experts

Dehydration of `1^(@)` alcohols like ethanol with conc . `H_(2)SO_(4)` at 413 K gives ethers .For example .
`underset("Ethylalcohol")(2CH_(3)CH_(2)OH)overset(conc H_(2)SO_(4)//413K)tounderset("Diethyl ethers")(CH_(3)CH_(2)-O-CH_(2))CH_(3)`
Mechanism : This is a nucleophilic himolecular reaction `(S_(N)2)` as shown below.
