Intermolecular Forces Review

What type of intermolecular forces do nonpolar molecules exhibit?

• Hydrogen bonding

• Dipole-dipole interactions

• Only London dispersion forces.

• Ionic bonding

What type of intermolecular forces does a polar molecule exhibit?

• Hydrogen bonding and ionic interactions.

• Dipole-dipole interactions and London dispersion forces.

• Covalent bonding and metallic bonding.

• Van der Waals forces and hydrogen bonding.

What is the significance of molecular shape in determining intermolecular forces?

• Molecular shape determines the color of the substance.

• Molecular shape affects polarity and the strength of intermolecular interactions.

• Molecular shape has no effect on intermolecular forces.

• Molecular shape only influences the boiling point of a substance.

Define electronegativity.

• The ability of an atom to lose electrons easily.

• The tendency of an atom to attract shared electrons to itself.

• The measure of an atom's size in a molecule.

• The energy required to remove an electron from an atom.

How do temperature and pressure affect intermolecular forces?

• Increasing temperature strengthens intermolecular forces, while increasing pressure weakens them.

• Increasing temperature can weaken intermolecular forces, while increasing pressure can strengthen them.

• Temperature has no effect on intermolecular forces, but pressure increases them.

• Both temperature and pressure have no effect on intermolecular forces.

What is the relationship between molecular weight and London dispersion forces?

• London dispersion forces decrease with molecular weight.

• London dispersion forces remain constant regardless of molecular weight.

• London dispersion forces increase with molecular weight.

• London dispersion forces are unrelated to molecular weight.

What is the difference between ionic bonding and covalent bonding?

• Ionic bonding involves the sharing of electrons, while covalent bonding involves the transfer of electrons.

• Ionic bonding involves the transfer of protons, while covalent bonding involves the sharing of neutrons.

• Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.

• Ionic bonding occurs only in metals, while covalent bonding occurs only in non-metals.

What is the effect of intermolecular forces on boiling points?

• Stronger intermolecular forces result in higher boiling points.

• Weaker intermolecular forces result in higher boiling points.

• Intermolecular forces have no effect on boiling points.

• Stronger intermolecular forces result in lower boiling points.
