What are good electrophiles for Sn1 reactions and why?
gpt
A 3° alkyl halide and benzylic halide are good electrophiles for SN1 reactions because they form stable carbocations after losing the halide, which are either due to inductive effects or resonance stabilization.
Explanation: Good electrophiles for SN1 reactions are those that form stable carbocations after losing the halide. A 3° alkyl halide forms a stable carbocation due to the inductive effects of the three surrounding groups, while benzylic halides form a stable carbocation due to resonance stabilization with the benzene ring.
