Q2 / 90 · JEE Main 2021 (27 Aug Shift 1) · Chemistry

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Synthesis of ethyl phenyl ether may be achieved by Williamson synthesis.

Reason (R): Reaction of bromobenzene with sodium ethoxide yields ethyl phenyl ether.

In the light of the above statements, choose the most appropriate answer from the options given below.

  • A
    Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)
  • Correct answer
    B
    (A) is correct but (R) is not correct
  • C
    (A) is not correct but (R) is correct
  • D
    Both (A) and (R) are correct and (R) is the correct explanation of (A)

Solution

Williamson synthesis Reaction

Figure

Reaction of bromobenzene with sodium ethoxide does not yields ethyl phenyl ether. Since, bromobenzene does not give nucleophilic reaction that easily.

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