Types of interparticle interactions

Question 1

What is a London Dispersion Forces (LDF)?

Answer 1

It is present in all molecules and caused by fluctuating electron distribution within atoms or molecules.

Weak type of intermolecular forces of attraction

Question 2

True/False. Any molecue with a dipole will be attracted to polar molecules.

Answer 2

True

Because it has regions of partial positive and partial negative.

Question 3

How does the strength of dipole-dipole interactions compare to LDF?

Answer 3

Dipole-dipole is stronger.

The existence of partial positive and partial negative results in a consistent and directional force.

Question 4

What is Dipole-Induced dipole forces?

Answer 4

It occur when a polar molecule induces a temporary dipole in a nonpolar molecule by distorting its electron cloud.

Nonpolar molecules can experience dipole-induced dipole interaction.

Question 5

What is hydrogen bonding?

Answer 5

Type of dipole-dipole interaction that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom.
