Question

Dispersion forces are _________________electrostatic attractions that occur due to the random electronic motion within all substances, ___________ those that are nonpolar. When the electrons within a molecule or atom are distributed asymmetrically about the nucleus, that molecule or atom will adopt a ___________, ___________ dipole. The presence of this dipole can then distort the electrons of a neighboring atom or molecule, producing an ___________ dipole. These two rapidly fluctuating dipoles thus result in a brief electrostatic _________ between the two species. These forces are stronger in ____________________ atoms and molecules. For example, dispersion forces between iodine molecules will be stronger than dispersion forces between fluorine molecules.

Answer 1

Answer:

1. Delicate

2. Such as

3. Shortlived, instantaneous

4. Induced

5. Attraction

6. larger and weighty

Explanation:

Dispersion forces are weak____electrostatic attractions that occur due to the random electronic motion within all substances, such as those that are nonpolar. When the electrons within a molecule or atom are distributed asymmetrically about the nucleus, that molecule or atom will adopt a shortlived, instantaneous _ dipole. The presence of this dipole can then distort the electrons of a neighboring atom or molecule, producing an _induced__ dipole. These two rapidly fluctuating dipoles thus result in a brief electrostatic _attraction_ between the two species. These forces are stronger in larger and weighty_ atoms and molecules. For example, dispersion forces between iodine molecules will be stronger than dispersion forces between fluorine molecules.
