Question

how anisole prepared by williamson's reaction ?

Answer 1

Preparation of anisole from Williamson's :

Answer 2

anisole can be prepared by the reacting sodium phenoxide( C6H5—O-Na+) ion with methyl halide(CH3—X). Mechanism for the reaction is in attached image.
Anisole can not be prepared by reacting halobenzene(C6H5—X) with sodium methoxide( CH3—O-Na+). Since in williamson reaction breaking of C—X bond occurs ,in halobenzene C—X bond has a double bond character due to the +R effect of —X, breaking of C=X become difficult.
