Does Sn1 Need Strong Nucleophile?

SN1 reactions nearly always involve weak nucleophiles, because strong nucleophiles are too reactive to allow a carbocation to form. ... Because SN1 reactions involve a carbocation intermediate, carbocation rearrangements can happen in SN1 reactions. They do NOT happen in SN2 reactions.

Does nucleophile strength matter in SN1?

The strength of the nucleophile does not affect the reaction rate of SN1 because, as stated above, the nucleophile is not involved in the rate-determining step.

Does SN1 depend on nucleophile?

The Rate Law Of The SN1 Reaction Is First-Order Overall

When we do so, we notice that the rate is only dependent on the concentration of the substrate, but not on the concentration of nucleophile.
