Which of the following anions is the best leaving group in an S_N1 reaction? A)F^- B)HO^- C)NH₂^- D)Cl^-

Question

Quizplus · Accepted Answer

In S_N1 reactions, the leaving group plays a crucial role in determining the rate of the reaction. The better the leaving group, the faster the reaction will proceed. Among the given anions, the best leaving group would be the one that can stabilize the negative charge after leaving the substrate. The leaving group stability primarily depends on the size and electronegativity of the atom or group. The larger and more electronegative an atom or group, the better the leaving group. In this case, among the given anions, Cl is the best leaving group because it is larger and more electronegative compared to the other anions.
