Abstract

Hydrocarbons including a methylene group are generally considered a hydrophobic building block, in the sense that the density of their hydration water is lower than that of bulk water. However, is the methylene group always hydrophobic? In this study, we experimentally determined the partial molar volume of a methylene group in water as 14.01 ± 0.46 cm
