What is the order of reactivity for halides (R-X) of a given alkyl group in both mechanisms (SN1 and SNN)?
Options
- AR–I > R–Br > R–Cl >> R–F
- BR–F > R–Cl > R–Br >> R–I
- CR–Cl > R–Br > R–I >> R–F
- DR–Br > R–I > R–Cl >> R–F
Correct answer
A. R–I > R–Br > R–Cl >> R–F
Step-by-step solution
The order of reactivity for halides (R-X) of a given alkyl group, and it is R–I > R–Br > R–Cl >> R–F in both SN1 and SN2 mechanisms.
