Which of the following solvents would best solvate fluoride ions (FC)? DMSO methanol hexane

Answer 1

Dimethyl sulfoxide (DMSO) is a polar aprotic solvent Methanol is a polar protic solvent Hexane non-polar solvent F- ion is a polar species which is best solvate in protic polar solvent because it also form hydrogen bond Solubility of any substance depends on the following fact "like dissolves like" Means polar solvent dissolve polar substances and non-polar dissolves non-polar substances. NaCi is polar compound which dissolve in polar solvent like water not in benzene,cH because CH is non-polar solvent The solubility of solute in solvent depends on the following factors: Solute Solvent Polar Non-polar Ionic Soluble Insoluble Polar Insoluble Soluble Non-Polar Insoluble Soluble Thus if solute is ionic or polar means it dissolves in polar solvents like water, acetone etc and if solute is non- polar means it does not dissolve in polar solvents like water, acetone
