In the light of the above statements, choose the most appropriate answer from the options given below.
- ABoth (A) and (R) are correct but (R) is NOT the correct explanation of (A)
- Correct answerB(A) is correct but (R) is not correct
- C(A) is not correct but (R) is correct
- DBoth (A) and (R) are correct and (R) is the correct explanation of (A)
Solution
Williamson synthesis Reaction

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'.
