The mechanism of Sn1 reaction is given as: R - X ⟶ R ⊕ X ⊖ ⟶ R ⊕ ‖ X ⊖ ⟶ Y ⊖ R - Y + X ⊖ lon pair Solvent Speparated ion pair A student writes general characteristics based on the given mechanism as : (a) The reaction is favoured by weak nucleophiles. (b) R ⊕ would be easily formed if the substituents are bulky y (c) The reaction is accompanied by r
Options
- A(a) and (b)
- B(a) and (c)
- C(a), (b) and (c)
- D(b) and (d)
Correct answer
C. (a), (b) and (c)
Step-by-step solution
Above reaction is S N 1 reaction as it proceed via formation of carbocation. Polar protic solvent is more suitable for S N 1 and recemisation takes place.
