Explanation

Williamson.s synthesis The formation of ether by the reaction of alkyl halides with sodium alkoxides, is known as Williamson.s synthesis. This reaction is given as below:
`underset(Ethylbromide)(CH_(3)CH_(2)^(+)Br^(-))underset("Sodium ethoxide")(Na^(+)O^(-)CH_(2)CH_(3))rarrunderset("Diethyl ether")(CH_(3)CH_(2))-O-CH_(2)-CH_(3)+NaBr`
This reaction involves the nucleophilic substitution of halide ion.
