The number of reactions that will give retention in configuration are :
Answer:
2
Solution:
(i) SOCl₂ (no pyridine) → SNi mechanism → retention
(ii) PBr₃ → SN2 → inversion
(iii) PCl₃ → SN2 → inversion
(iv) SOCl₂ / pyridine → SN2 → inversion
(v) Williamson ether synthesis → reaction at O, not C → retention
Answer: 2 reactions (i, v)
