On the polarity of partially fluorinated methyl groups

► Preparation of model compounds in a series involving mono-, di-, and trifluoro-organic compounds. ► Examination of effects on log P in the series. ► Correlation to dipole derived from computations. ► Confirmation of the polarity trends of CH3 < CF3 ≪ CH2F ∼ CHF2 that have been previously observed in part for propylbenzene.
