The best way to prepare tert-butyl methyl ether by Williamson synthesis is

  1. Asodium methoxide with 2-chloro-2-methylpropane
  2. Btert-butyl alcohol with sodium iodide
  3. Csodium methoxide with 2-methylpropan-2-ol
  4. Dsodium tert-butoxide with iodomethane

Answer: D

The halide must be primary (methyl) for SN2 substitution. A tertiary halide with the strongly basic methoxide undergoes elimination, giving 2-methylpropene. So and are used.
