Given the following substitution reaction, what would the effect be of changing the solvent from CH3OH to (CH3)2S=O?
CH3(CH2)5Br + NaOH as it goes to CH3(CH2)5OH + Br-
A) The rate would increase because SN2 reactions favor a polar aprotic solvent.
B) The rate would decrease because SN1 reactions favor a polar protic solvent.
C) The potential change cannot be predicted.
