SN2 E2 SN1 E1
Substrate CH3 > 1o > 2o 3o > 2o > 1o 3o > 2o 3o > 2o
Nucleophile/Base strong nuc strong base weak nuc weak base
Solvent polar aprotic polar aprotic* polar protic polar protic
Leaving Group good good good good

*E2 reactions are slower in polar protic solvents than polar aprotic solvents but still work well in either.
