When NaCl dissolves in water,

Question

aqueous Na and Cl- ions result. The force of attraction that exists between Na and H20 is called a(n) _______ interaction.

dipole-dipole

ion-ion

hydrogen bonding

ion-dipole

london dispersion force

Answer 1

The bond between Na and Cl in solid NaCl is essentially an ionic bond which is an electrostatic attraction between oppositely charged ions.   This would be ion-ion attraction.

Answer 2

Ion-dipole

Explanation: Na is a positive ion (Cation) when dissolved in water.

H2O is polar. The H has a partial positive charge as the O has a partial negative charge. This partial charge is called dipole. So the answer is an ion(Na+) - dipole(O-) interaction.

Hope that helped.

Answer 3

i took the chemistry regents in NYC and got a 68. i think its an ion-dipole interaction
