Nacl is an ionic solid. the na+ and cl− ions in nacl are bonded through an electrostatic force of attraction commonly known as the ionic bond. water is a polar solvent. the oxygen atom, being more electronegative, attracts the electron cloud toward itself. as the electron cloud is pulled by the oxygen atom, it carries a partial negative charge, and the hydrogen atoms carry a partial positive charge. this partial separation of charges in the water molecule makes it polar. predict which intermolecular forces contribute the most to the dissolution of nacl in water. check all that apply.
