What are the basics of SN1 and E1 reactions?
SN1: substitution, nucleophilic, unimolecular. E1: elimination, unimolecular. Often simultaneous, both involve carbocation. Read More »

You cannot do Sn1 or Sn2 on an sp2 center. The reaction only works with sp3 centers. It has to do with the way the LUMO on the electrophile is positioned. A LUMO on an sp3 center is a sigma* antibonding orbital - easily attacked by the lone...

Increasing the polarity of the solvent increases the reaction rate because the leaving group and carbocation (both very polar species) are better stabilized by polar solvents (like dissolves like).

Solvent effects [for SN1 reactions] Since the SN1 reaction involves formation of an unstable carbocation intermediate in the rate-determining step, anything that can facilitate this will speed up the reaction. The normal solvents of choice ...
