Q5 / 110 · VITEEE 2024 · Chemistry

Which of the following cannot be made by using Williamson synthesis?

  • A
    Methoxybenzene
  • B
    Benzyl-p-nitrophenyl ether
  • C
    tert-butyl methyl ether
  • Correct answer
    D
    Di-tert butyl ether

Solution

Since $3^{\circ}$ alkyl halides prefer to under go elimination rather than substitution, therefore sodium tert-butoxide react with tert-butyl bromide or chlorides to form elimination product isobutylene rather than substitution product di-tert-butyl ether. Figure

Hence, the correct answer is option: 'D'.
