SN1 Reactivity 1 Flashcards
SN1 has
a two step reaction
what does SN1 Stand for
subsitution nucleophilic unimolecular
what is the rate determining step?
it dependant of the substrate and how long it takes for the leaving group to leave the substate .
why is the rate determining step the formation of the carbocation?
The formation of a carbocation is not energetically favored, so this step in the reaction is the slowest step and determines the overall rate of the reaction.
the reaction between nucleophile and carbocation is
energetically favorable
what is formed when nucleophile attacks
a racemic solution of enantiomers
why do enantiomers form in SN1
the carbocation is planar. the nucleophile can attack from either sides
the strength of the nucleophile
does not effect the rate of SN1
What increases the likelyhood of sn1
the stability of the carbocation tertiary carbocations afe more likely to do SN1
