Pairing and Carbon Acidity

Filled squares are for cesium ion pairs and fiUed diamonds are for lithium ion pairs in THF. Open circles are for cesium ion pairs in CHA. For convenience, a line with slope = 1 and intercept = 0 has been placed on the plot. 

If ion-pair dissociation constants, K and are roughly the same, which tends to be true for hydrocarbons, then the ion-pair Ki and true, free-ion values will be
