Which one of the following methods is used to prepare Me \(_{3}\) COEt with a good yield?
- A Mixing EtONa with MegCCl
- B Mixing Me \(_{3}\) CONa with EtCl
- C Heating a mixture of \((1 ; 1)\) EtOH and \(\mathrm{Me}_{3} \mathrm{COH}\) in the presence of conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\)
- D Treatment of Me_COH with EtMgI
Answer & Solution
Correct Answer
(B) Mixing Me \(_{3}\) CONa with EtCl
Step-by-step Solution
Detailed explanation
\(\mathrm{Me}_{3} \mathrm{CONa} \underset{\left(1^{\circ} \text { alkyl halide) }\right.}{\stackrel{\mathrm{EtCl}}{\longrightarrow}} \mathrm{Me}_{3} \mathrm{COEt}\) This reaction is known as Williamson's synthesis. So, the correct option is B
