Problem
In a correct particulate-level diagram of an aqueous solution that contains dissolved Cl⁻ ions, how should individual water molecules be oriented relative to a given Cl⁻ ion to depict the predominant ion–dipole interaction?
(a) The oxygen atom of each water molecule points toward the Cl− ion.
(b) Water molecules are randomly oriented because the Cl− ion does not interact specifically with water.
(c) The two hydrogen atoms of each water molecule point toward the Cl− ion.
(d) Both hydrogen atoms point away from the Cl− ion to reduce repulsion between the oxygen atom and the ion.
