Question

ionic compounds are soluble in water due to.
1) Hydrogen Bonding
2) Ion-Dipole forces
3) Dipole dipole forces
4) Dipole induced Dipole forces​

Answer 1

Answer:

3 option is correct (dipole force)

Answer 2

Answer:

The correct answer is (2) Ion-dipole forces.

Explanation:

• An ionic compound, like $NaCl$, is made up of cations and anions.
• When this ionic compound is added to water, it breaks into cations and anions. These ions get hydrated by the water molecules.
• A water molecule has a permanent dipole and is polar. There exists a partial negative charge on oxygen and a partial positive charge on each hydrogen.
• The cation attracts the negative pole of the water, that is the oxygen.
• The anion attracts the positive pole of the water, that is the hydrogen.
• This establishes an interaction ion-dipole force between ions and polar molecules.

Conclusion:

Ionic compounds are soluble in water due to ion-dipole forces.
