Question

When NaCl dissolves in water, aqueous Na+ and Cl- ions result. The force of attraction that exists between Na+ and H2O is called a(n) __________ interaction. Select one: a. dipole-dipole b. ion-ion c. hydrogen bonding d. ion-dipole e. London dispersion force

Answer 1

Answer:

b. ion-ion

Explanation:

When NaCl dissolves in water , it dissociates completely into the corresponding ions , i.e. , Na⁺ and Cl⁻ ,

Since , the charges have complete positive and negative charges , hence , they interact with each other via ion - ion interaction , i.e. the interaction between the positive and negative charges , is referred to as ion - ion interaction .

Hence , the correct option is b. ion-ion interaction .
