The Total solution for NCERT class 6-12
Preparation of ethers by acid dehydration of secondary ortertiary alcohols is not a suitable method. Give reason.
The formation of ethers by dehydration ofalcohol is a bimolecular reaction (SN2) involving the attackof an alcohol molecule on a protonated alcohol molecule. In the method, thealkyl group should be unhindered. In case of secondary or tertiary alcohols,the alkyl group is hindered. As a result, elimination dominates substitution.Hence, in place of ethers, alkenes are formed.
