MCQ
Which of the following reactions is possible?
  • A
    Me3​C−ONa + Me3​C−Br → Me3​C−O−CMe3​
  • B
    Me2​CH−ONa + Me2​ + Me2​CHMe2​CHBr → Me2​CH−O−CHMe2​
  • C
    PhONa + PhBr → PhOPh
  • D
    PhONa + CH3​Br → PhOCH3​
✓

Answer

  1. PhONa + CH3​Br → PhOCH3​

Explanation:

Six types of ethers cannot be prepared by Williamson's synthesis.

Not feasible, RX = 3°, RONa = 3°

Not feasible, RX = 2°, RONa = 2°

Not feasible, ArX,

Feasible, RX = 1°, ArONa
