Intermolecular Forces and Molecular Properties

Flashcards covering key concepts of intermolecular forces, molecular states, and relevant chemical interactions.

What increases the boiling point of molecules?

The larger the molecules, the higher the boiling point due to increased intermolecular forces.

How are dipole-dipole interactions different from dispersion forces?

Dipole-dipole interactions are stronger than dispersion forces, which are generally weaker.

What effect do electron density and electronegativity have on molecular interactions?

Higher electronegativity leads to stronger dipole moments, affecting the strength of intermolecular forces.

What is the state of chlorine at room temperature?

Chlorine is a gas at room temperature.

What type of intermolecular forces exist between nitrogen molecules?

Nitrogen molecules experience London dispersion forces.

Which intermolecular force is responsible for holding water molecules together?

Water molecules exhibit dipole-dipole interactions due to their polar nature.

What type of interaction occurs when comparing carbon monoxide to octane?

Both have dispersion interactions, but carbon monoxide is polar while octane is nonpolar.

What is the significance of electron movement in determining states of matter?

The movement and arrangement of electrons influence whether a substance is a solid, liquid, or gas.

What are ion dipole interactions dependent on?

Ion dipole interactions depend on Coulomb's law, which involves charge, distance, and the strength of the ion.

Why can a fly walk on a ceiling?

A fly can walk on a ceiling due to many dispersion interactions between its legs and the surface.
