In a Williamson synthesis, an ether is formed by reacting an alcohol and a alkyl halide in the presence of a base.
To form the ether R-O-R', one starts with R-OH and R-X, where X is a halogen, typically bromine or chlorine. When mixed with the base, like NaOH, the alcohol is deprotonated, leaving a negatively charged oxygen. This acts as a nucleophile and attacks the carbon bonded to the halogen. The halogen, a good leaving group, is released, leaving behind R-O-R'.
This reaction works the best when using primary alcohols and halogens, and will not go at all with tertiary alkyl halides. Ideally, the halide should be on the less substituted of the R groups.
Williamson Ether Synthesis is a type of chemical reaction. If an individual is wanting to learn more about this chemical reaction, they may take college level courses in chemistry. Additionally, there are many books on chemistry which have information on Williamson Ether Synthesis.

Williamson synthesis, or Williamson ether synthesis, is a way to make ethers from alcohols and alkyl halides. For example, if you add CH3CH2Br to CH3CH2OH you make diethyl ether (CH3CH2OCH2CH3).

Oxidation
The Williamson ether synthesis is a reaction that converts alcohols (R-OH) into ethers (R-O-R). The first step in this reaction is forming the conjugate base of the alcohol (called an alcoxide) by reacting the alcohol with sodium metal. This reaction forms hydrogen gas (H 2 ) as a biproduct, so if you perform this reaction take caution to keep all flame sources away during sodium addition.  The alcoxide can then be added to a suitable alkyl halide (typically a primary halide) to form the ether via anSN2 mechanism.  Example: An example of the Williamson ether synthesis to make diethyl ether.  However there are certain limitations of Williamson synthesis of ether. In Williamson Synthesis the attack is done by alkoxide ion. Alkoxide ion behaves as the neuoclophile as well as the base. When it behaves as the neuclophile it causes substitution reaction to occur the formation of ether. When it behaves as the base it causes the the elimination reaction to occur. With the formation of alkenes. These two reaction going from primary to secandory to tertiary alkyl halides.possibility of elimination reaction goes on increasing with the formation of more amount of alkene and less amount of ether .
