COMEDK · Chemistry · 26. Alcohols Phenols and Ethers
Two statements, Assertion and Reason are given below. Choose the correct option.
Assertion: n-propyl tert-butyl ether can be readily prepared in the laboratory by Williamson's synthesis.
Reason: The reaction occurs by \(\mathrm{S}_{\mathrm{N}} 1\) attack of Primary alkoxide on Tert-alkyl halide to give good yield of the product, n-propyl tert-butyl ether.
- A Assertion is incorrect but reason is correct.
- B Assertion is correct but Reason is incorrect.
- C Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
- D Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Answer & Solution
Correct Answer
(B) Assertion is correct but Reason is incorrect.
Step-by-step Solution
Detailed explanation
Assertion is correct: n-propyl tert-butyl ether can be prepared by Williamson synthesis by reacting sodium tert-butoxide (tertiary alkoxide) with 1-bromopropane (primary alkyl halide) via \(S_N2\). Reason is incorrect for two reasons: Williamson synthesis proceeds via \(S_N2\),…
