The total number of S _ N 2 (nucleophilic substitution bimolecular) reactions involved in the following reaction sequence is
Options
- A3
- B4
- C2
- D5
Correct answer
A. 3
Step-by-step solution
Total number of S _ N 2 reactions involved in the reaction is three. In first S _ N 2 reaction methoxy group is replaced by OH group (i.e. CH ₃ group replace by H ⁺ of HI ). In second S _ N 2 reaction another methoxy group get replaced by OH . In third S _ N 2 reaction OH get replaced by iodide group.
