The acidity ladder scale in [BMPY][NTf2] was successfully expanded toward the weak acidity region for about five more pK units compared to the previously established one. This allows the acidities of a series of 13 aliphatic and aromatic nitroalkanes to be determined accurately by the UV–vis spectroscopic method. The acidity of nitroalkane in [BMPY][NTf2] covers ∼8 pK units and is significantly weaker
