Intermolecular Forces

Front

What type of intermolecular force is present in Cl₂?

Back

Dispersion forces (London dispersion forces) are the only intermolecular forces present in Cl₂.

Front

What are the intermolecular forces present in CO₂?

Back

The intermolecular forces in CO₂ are dispersion forces.

Front

Which molecule would dissolve in oil: CCl₄ or H₂O?

Back

CCl₄ would dissolve in oil because it is nonpolar, while H₂O is polar.

Front

Rank the following intermolecular forces from strongest to weakest: covalent bond, London forces, hydrogen bond, dipole-dipole attraction.

Back

Covalent bond > Hydrogen bond > Dipole-dipole attraction > London forces.

Front

What explains the high boiling point of water?

Back

The high boiling point of water is explained by hydrogen bonding.

Front

Define dispersion forces.

Back

Dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is the significance of hydrogen bonding in water?

Back

Hydrogen bonding in water leads to its high boiling point, high specific heat, and unique solvent properties.

Front

How do dipole-dipole interactions differ from dispersion forces?

Back

Dipole-dipole interactions occur between polar molecules, while dispersion forces occur in all molecules but are significant in nonpolar ones.

Front

What is the relationship between molecular polarity and solubility?

Back

Polar molecules tend to dissolve in polar solvents, while nonpolar molecules dissolve in nonpolar solvents.

Front

What factors affect the strength of intermolecular forces?

Back

Factors include molecular size, shape, polarity, and the presence of functional groups.
