1. The problem statement, all variables and given/known data Which would be the stronger nucleophile in a polar aprotic solvent? a) H2O or H2S b) (CH3)3P or (CH3)3N 2. Relevant equations 3. The attempt at a solution I'm really confused because in my book, it says that in protic solvents, the larger atoms (I-) are stronger nucleophiles than smaller ones (F-). Then it says that it is opposite for when it is an aprotic solvent (e.g. F- is more nucleophilic than I-) In this case, the answer to b) is H2S and c) is (CH3)3P, but shouldn't it be the opposite??
