REACTIVITY
The reaction rate is sensitive to electronic
factors
which govern the stability of the carbocation
intermediate.
RCH2-X << R2CH-X < R3CX
1o 2o 3o
increasing rate
increasing
stability of C+
The formation of the ionic intermediate
is
favoured with polar solvents & we are
therefore able to control the reaction so that
either the SN2 or SN1 mechanism will occur.
