Question

CH3MgXCH3COOC2H5ANaBC2H5BrC
Here, C is :

  1. C2H5OC2H5
  2. CH3COOC2H5
  3. (CH3)3COC2H5
  4. CH3COOCH3

A
C2H5OC2H5
B
(CH3)3COC2H5
C
CH3COOC2H5
D
CH3COOCH3
Solution
Verified by Toppr


In first step

CH3MgX+CH3COOC2H5dryether−−−−(CH3)3COH+C2H5OMgX

Here the tertiary butyl alchol formed which then reacts with Na to give (CH3)3CONa+0.5H2

So when there is primary alkyl halide reacts with alkoxide then Williamson's ether synthesis takes place rather than elimination.

Williamson's ether synthesis goes through the SN2 mechanism.

Option D is correct.
