FLASHCARD QUESTION

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

2.

FLASHCARD QUESTION

Front

What is the strongest type of intermolecular force?

Back

Hydrogen bonding is the strongest type of intermolecular force, occurring between molecules that have hydrogen atoms bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

FLASHCARD QUESTION

Front

What is the relationship between intermolecular forces and boiling point?

Back

The stronger the intermolecular forces, the higher the boiling point of a substance, as more energy is required to overcome these forces.

FLASHCARD QUESTION

Front

What are dipole-dipole attractions?

Back

Dipole-dipole attractions are intermolecular forces that occur between polar molecules, where the positive end of one molecule is attracted to the negative end of another.

FLASHCARD QUESTION

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and a negative end.

FLASHCARD QUESTION

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, occurring in all molecules, whether polar or nonpolar.

FLASHCARD QUESTION

Front

How do hydrogen bonds affect the properties of water?

Back

Hydrogen bonds give water its high boiling and melting points, surface tension, and ability to dissolve many substances, making it a unique solvent.
