What forces.....?

Sodium chloride is next to insoluble in ethanol.

Ion-dipole forces are involved when sodium chloride dissolves in ethanol.

#"NaCl"# is not very soluble in ethanol, but it does dissolve to the extent of 0.65 g of #"NaCl"# per kilogram of ethanol.

The strongest forces in #"NaCl"# are the ion-ion attractions between #"Na"^"+"# and #"Cl"^"-"# ions.

The strongest forces in ethanol are the dipole-dipole forces we call hydrogen bonds.

The strongest forces in a solution of #"NaCl"# in ethanol will be ion-dipole forces.

Just as they do in water, the #"Cl"^"-"# ions are attracted to the partially positive #"H"# atoms in the #"OH"# groups of ethanol.

The #"Na"^"+"# ions are attracted to the partially negative #"O"# atoms in the ethanol.
