What forces.....?

#### Explanation:

Sodium chloride is next to insoluble in ethanol.

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

#### Explanation:

$\text{NaCl}$ is not very soluble in ethanol, but it does dissolve to the extent of 0.65 g of $\text{NaCl}$ per kilogram of ethanol.

The strongest forces in $\text{NaCl}$ are the ion-ion attractions between $\text{Na"^"+}$ and $\text{Cl"^"-}$ ions.

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

The strongest forces in a solution of $\text{NaCl}$ in ethanol will be ion-dipole forces.

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

The $\text{Na"^"+}$ ions are attracted to the partially negative $\text{O}$ atoms in the ethanol.
