Chapter 18, Problem 9RAT

Solution

To determine: The correct option for the statement “Why are ion-dipole attractions stronger than dipole-dipole attractions?”

Answer:

The correct option for the statement “Why are ion-dipole attractions stronger than dipole-dipole attractions?” is option (d).

Explanation:

The dipole is basically the segregation of charges. It occurs because of the difference in the values of electronegativities.

The ion-dipole interactions are basically the interactions existing between the ion and the dipole of any polar molecule.

The dipole-dipole interactions are basically the interactions existing between any two polar molecules.

The dipole in polar molecules occurs because of the difference in the value of electronegativities and it generates partial charges on atoms.

The magnitude of charge existing on any ion is stronger compared to the partial charges existing in the dipole.

Thus, ion-dipole attractions are way stronger compared the dipole-dipole attractions.

Conclusion:

Therefore, the correct option for the statement “Why are ion-dipole attractions stronger than dipole-dipole attractions?” is option (d).
