Malononitrile in Aromatic Solvents—Geometry of Solvation

Abstract

Polarization and electric birefringence measurements are reported for malononitrile in dioxan , benzene and hexafluorobenzene solutions. These data, together with ¹H n.m.r .shifts, are used to explore solute-solvent interactions. Changes in the proton shifts of CH₂(CN)₂ are studied with replacement of benzene solvent by fluorinated benzenes.
