Ionic liquids have attracted wide attention lately and their potential applications in different areas have been explored. Most of the current researches on ionic liquids are concentrated on investigating what can be done by ionic liquids and why they work the way they do. The latter provide the insight into the molecular factors that determine their properties ranging from quantitative thermodynamic and physical data and qualitative tends that guide in searching the best ionic liquids for particular purpose. Many of the applications rely upon the interaction of ionic liquids with other components. Ionic liquids exhibit nanoscale phase segregation into polar and nonpolar- regions. The nanoscale selforganisation is the result of interplay between Coulomb and van der Waals interactions which leads to the formation of high charge density permeated non-polar regions. This characteristic determines how different molecular solutes interact with certain domain of the ionic liquids and distinct local environment. However, the complexities of the nature and size of cation-anion interactions and intermolecular forces in liquids phase give rise to controversies. This review discusses the current development in understanding molecular structure, cation- anion interaction, intermolecular forces and their effects of solvation. This work is mainly concentrated on imidazolium based ionic liquids. Keywords: Solute–Solvent Interaction, Imidazolium based Ionic Liqui
