What is the name of the reaction that forms an ether?

The formation of an ether typically occurs through a process known as dehydration synthesis, also called condensation reaction. In this reaction, two alcohol molecules react together, resulting in the elimination of a water molecule and the formation of an ether linkage (R-O-R). The general mechanism involves the nucleophilic attack of one alcohol on the other, leading to the formation of the ether bond while releasing water.

This reaction is key in organic synthesis as it allows for the creation of ethers, which are significant classes of compounds used in various applications such as solvents and intermediates in chemical reactions. The specificity of dehydration synthesis for ether formation distinguishes it from the other reactions listed, as hydrolysis refers to the breaking down of compounds by water, oxidation involves the addition of oxygen or loss of hydrogen, and reduction refers to the gain of electrons or hydrogen, all of which do not yield ethers directly.
