3
Q
the rate determining step relies on
A
substate and nucleophile
4
Q
SN2 attacks from
A
the back side of leaving group
5
Q
why can it not attack from the front?
A
the leaving group - which is also an electron-rich group - blocks the way.
6
Q
what does it mean when it then attacks from the back side
A
the stereochemical configuration at the central carbon inverts as the reaction proceeds.
7
Q
At the transition state what plane does the carbon and the ligand attached lie on
A
the same plane.
8
Q
SN2 are
A
inherently stereoselective:
9
Q
SN2 is
A
one step mechanism
10
Q
what slows down the SN2 rate?
A
steric hindrance
11
Q
what carbon is best for SN2
A
primary
