Iverson CH320M Final Flashcards

For SN2 reactions __________ are most reactive whereas in SN1 reactions __________ are most reactive

Primary, Tertiary

Whats the difference in the first step of an SN1 reaction compared to the first step of an SN2 reaction?

The first step of an SN2 reaction is the nucleophile attacking the electrophile while the first step of an SN1 reaction is the leaving group leaving

In SN1 reactions the __________ of the __________ is most important

stability, carbocation

1° and 2° substrates are more likely to be __________

SN2

Good leaving groups are often __________

Conjugate Bases

__________ speed up the rate of SN2 reactions

polar aprotic solvents

Cl^-

Nucleophile only

Br^-

Nucleophile only

In order to identify the mechanism of a reaction first __________ and then __________

identify the function of the reagent, identify the substrate

If you have a nucleophile who’s conjugate acid is strong then its a __________

weak base/strong nucleophile
