The reaction represents Williamson’s synthesis.
An alkyl halide is to be primary, so a nucleophilic substitution reaction occurs. Because with tertiary alkyl halides, alkenes are formed. Alkoxides are nucleophiles and strong bases.
- The Williamson ether synthesis is an SN2 reaction in which an alkoxide ion is a nucleophile that displaces a halide ion from an alkyl halide to give an ether.
