One the practice problems i was doing in preparation for my exam was to rank the following nucleophiles in the order of decreasing reactivity, best nucleophile first.
Nucleophiles: CH3OH, Br-, NH3, F-, CH3S-
The answer was CH3S->Br->NH3>F->CH3OH
What I don't understand is why CH3S- is a stronger nucleophile than the bromide ion, shouldn't bromide be stronger because it's a bigger atom and thus have more polarizability?
