Williamson's synthesis involves

  • A
    $\mathrm{S}_{\mathrm{N}} 1$ mechanism
  • B
    nucleophilic addition
  • Correct answer
    C
    $\mathrm{S}_{\mathrm{N}} 2$ mechanism
  • D
    $\mathrm{S}_{\mathrm{E}}$ mechanism

Solution

When sodium or potassium alkoxide is heated with an alkyl halide to give ether, this reaction is known as Williamson's synthesis. $$ R \mathrm{ONa}+R^{\prime} X \longrightarrow R-\mathrm{O}-R^{\prime}+\mathrm{Na} X $$ This is an example of nucleophilic substitution and follow $\mathrm{S}_{\mathrm{N}} 2$ mechanism.

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