Ethers can be formed under acidic or basic conditions. What are the limitation of forming an ether from an alcohol under acidic conditions? I. Asymmetrical ethers cannot be formed exclusively under acidic conditions II. Rearrangement in the carbon skeletal backbone is possible under acidic conditions, III. Ethers in which the carbon bound to oxygen is 3° are not possible. IV. Intramolecular cyclization reactions are not possible under acidic conditions.
