Which information below regarding this reaction is applicable?
- A It follows \(\mathrm{S}_{\mathrm{N}} 2\) pathway, because it is a primary alkyl chloride.
- B It follows \(S_{N} 1\) pathway, because the intermediate carbocation is resonance stabilized.
- C \(\mathrm{S}_{\mathrm{N}} 1\) pathway is not followed, because the intermediate carbocation is destabilised by \(-1\) effect of oxygen
- D A mixed \(\mathrm{S}_{\mathrm{N}} 1\) and \(\mathrm{S}_{\mathrm{N}} 2\) pathway is followed.
Answer & Solution
Correct Answer
(D) A mixed \(\mathrm{S}_{\mathrm{N}} 1\) and \(\mathrm{S}_{\mathrm{N}} 2\) pathway is followed.
Step-by-step Solution
Detailed explanation
Hint: \(\mathrm{S}_{\mathrm{N}} 2\) is also facilitated by OH due to resonance stablization of transition state.
